I absolutely plan on pursuing a tube mod for the Oppo BDP-105 that will be similar to and if anything, better than, the tube stage and supply that we use in the Oppo 95. I don't know when these will be released and of course there is not only a price difference in the units ($1200 for 105 vs. $499 for 103), but our tube mods will be no LESS than $2K.
So, my question is, is there interest in a lesser cost, non-tube mod for the Oppo 103? If there is sufficient interest, then we can start working on this right away.
Please post your thoughts here as I am greatly interested.
Sincerely,

I am interested in mods for 103. Excited to see what you have to offer for 103. Surprised nobody at AC has shown interest yet for mods on 103.
-
Well, everyone is waiting for the 105 mods I believe, but they are two different products and the mods are at two distinctly different price-points.
The tube mod for the $1200 Oppo 105 will be $2K+.
The mod that I am considering for the $500 103 would be in the $500-$750 range and not include tubes.
Thank you for your interest and lets see if there are others. To be honest, I have to have interest, if I am going to spend the time to develop the mod. The interest is significant in the 105 I already know. I would expect there to be interest in the 103 mods also, as I expect that stock unit is a GREAT BARGAIN for $500 and offers SO much already.
Sincerely,
Dan W.

I just received my BDP 103. I use it to play back multi-channel files from my PC via HDMI. What do you have in mind for this unit given its modest DAC chip and output stage?

The 105 will retail for about $1200. The 103 retails for about $500. Unless the mods make the 103 sound better than a 105 I dont see a value proposition.
-
I'd be very interested in mods for the 105 but would prefer something in the $1K range (vs. the $2K tube-based mods you envision).
-
On second thought, I might opt for the tube mod myself. Dan - from the time you get a 105, what is the timeframe for you to design, test and formally introduce the mods?
-
I don't think DAN will be ready to MOD the 105 until June, my guess.
-
If the Mod for the 103 is similar to the SS mod on the BDP 95, it will be very worthwhile. Really is a substantial upgrade IMO. Of course the tube mod is better, but I was really happy with that SS mod. Could really hit the sweet spot for more budget constrained audiophiles.
-
I'm sure many would be interested in an awesome discrete-output solid state 2-channel mod for the Oppo 105 that costs significantly less than the tube mod.
I really think Oppo has raised the bar by implementing asynchronous USB input for the 105, but personally they should have not bothered with the headphone output and decrease the price instead.
-
Hi and thank you all for your feedback.
First of all, it will NOT be as late as June before we have the tube mod for the 105. If they release the unit by year's end as anticipated, it will not take long to get the tube mod worked out for the 105. We will start with the existing mod board for the 95 and adapt the overall layout to allow for installation in the 105. From there, I have some ideas for improving both the power supply and tube circuit. Because of how they have split the outputs from the multi-DAC Saber module, I will have to work out the best way to do this.
We also already have a discrete circuit design that could be adapated to the this unit and would be at a lesser cost than the tube mod.
I will of course entertain both options. I just need to get my hands on a 105.
RE the 103, point is well made! Given the $700 price difference, if we were to produce a $500-$700 mod for the 103, it would HAVE to outperform the 105.
A possible misconception here also, is that the Crystal Semi DAC used in the 103 is an 'inferior' product. To be honest, Crystal has produced EXCEPTIONAL DACs for quite some time, and the analog stage for the 103 was redesigned by a sharp designer that I know and have worked with. I don't like the fact that the 103 uses only a switched mode power supply. THAT is a weak point, in my opinion.
I will investigate both and see what we can do!
Perhaps I should bring in a 103 and start there! Anyone interested in having us take a look at their 103? In return, you would receive a VERY good discount on the new mod developed.
Thanks,
Dan Wright

Hi Dan. Just spoke with Christine. I will send my 105 asap. My 105 just shipped from Oppo, and I am only 1 1/2 hours away from them. I am truly excited to have the best modder in the business work on my 105!
-
I am excited to start working on it! I expect it will only take a few weeks to have the mods finalized!
Thanks!
Dan

Dan, I am having my 105 sent directly to you from Oppo. :thumb:

Dan,
Some folks at AVS Forum have pointed out that the new 105, compared to the 95, is AC coupled instead of DC coupled, and also that the DAC channels are no longer stacked. As you dig into the new 105, I'd be curious to hear your thoughts on these design choices and whether this makes the 105 an inferior product to the 95.

Dan, the short answer is yes!
I have your Oppo tube mod for the 95 and love it. I also have the full solid state mod for the HT on a 83 SE. I would think a 103 solid state full channel mod would work great for the HT rig.

Dan has my 105 now. I will let him discuss his findings, but I can say with certainty, he is blown away by what he found under the top cover. It his on a much higher level than the 95 :thumb:

OK guys, first of all, updates on the units as I have both stock 103 and 105 in house right now, thank you to customers who opted to let me use their units develop the mod!
The stock 105 IS superior sounding, to my ears, to the stock 103. Not even needing an A/B. The 103 is GOOD, but has the sound that I find typical with units powered by a SMPS (Switched mode power supply) and with cap coupled outputs....Perhaps you can already see where I am going on the 103 front!
The 105 on CD only so far, is REALLY good stock! I am surprised at how good it is, to be honest. Oppo REALLY stepped up their game with this unit, improving the power supply design and overall chassis design. They also added SPDIF and USB digital inputs. I have not listened to USB inputs yet, but will do so today and report back with my findings there!
It is true that they split out the 8 DACs, in a different way than the 95, where they stacked four DACs per channel. At least one pair is used for the Headphone outs, and the rest are split between balanced outputs and single-ended outputs. Not really sure why, but based on Q&A from Oppo, it was to give greater separation between SE and balanced outs. Now in my mind, a person will EITHER be using it via RCA or XLR and will either be listening to headphones, or speakers. Not really sure why they felt the need to separate all outputs like this. With our tube mods, I will experiment to see how best to utilize the 8 DACs on the chip, with the end result being, that XLR, RCA and headphone outputs ALL benefit (i.e. are fed exclusively) from our balanced tube circuit.
The other question is, what does the SMPS supply, in the 105? It appears that their linear, regulated supply, already powers the DACs and analog stages. Not sure if it powers the digital input circuitry. I would expect that video is relegated to the SMPS and as such, it is POSSIBLE that we will offer an upgrade to this supply, including a new, linear, regulated supply instead.
I am also going to consider a discrete SS analog stage for the 105, at a lower price than the tube stage, as it will of course, not require the outboard tube supply or umbilical.
I am going to be finishing the first PCB for the 103 today and I could nearly put the 95 mod directly into the 105 as it is. The 95 tube mod will be the basis for the 105 mod, with plans to upgrade the external tube supply as well as the tube analog stage. I also have to determine how the eight DACs on the chip will be used.
I expect to have reports back on both mods in the next two weeks!
The 95 mod benefited from a years worth of R&D into the Sony XA-5400ES mod. The 105 benefits from the R&D developed from the 95 mod. We are not re-inventing the wheel in this case! Rather, we are streamlining and improving the performance of the 'wheel' for the 105 and adapting to the design changes in the new unit. Because of this, it will NOT take long to have the mod finalized!
Once the mod design is complete, we will be able to turn units around in a 2-week time frame.
If you are interested, please contact us NOW and Kristin will add your name to a list that she has already started compiling. We will contact those from the list, from the top, once the mods are complete and schedule start dates from there.
The 103 and 105 are BOTH very exciting units!
If the results of my work meet my expectations:
The 103 will be a FANTASTIC machine for ~$1K, that will perform very well for audio, both 2CH and MCH and will be improved in both its performance as a video player and a transport for feeding digital audio to a pre/processor.
The 105 will be a WORLD CLASS player AND DAC, with our tube analog stage, for < $3500 and will perform at the $10K+ range ABSOLUTELY! We may also offer an upgrade option to the SMPS that will further improve video playback! I will investigate a SS mod for the 105 that is likely 1/2 the price of the tube mods.
Thank you for your interest in our work!

Thank you for the updates, Dan! Exciting stuff, for sure. :green:
-
That all sounds great Dan! I'll be eagerly awaiting further developments.
Curious if you could comment on STOCK sound of the 105 as opposed to the stock 95. Is the new Oppo starting at a better place as far as the analog section goes, or is it about the same?
-
Dan,
Based on your observations, would be interested in a full channel solid state mod for the 105 unit.

Dan, I too would like to get your thoughts on the stock 105 vs. the stock 95.
I also vote for a SS mod!
Thanks for all your great comments so far, Dan! :thumb:

I was once asked years ago about putting tubes in a SS mod that we were doing. I was told "Make it Glow!". We have been doing this every since!
(http://www.audiocircle.com/image.php?id=71200)
The first Oppo BDP-105. Mod work is still in progress, but tubes are installed and I am evaluating two versions of our external power supply - current and upgraded design that I developed a while back, but had not implemented until now.
There is still more work to do, but I wanted everyone to know that it is playing music via our tube stage, XLR and RCA and it sounds FANTASTIC.
Based on how Oppo has built this unit, it is unlikely that the headphone out will benefit from tube analog outputs, but both RCA and XLR will and for ALL formats of course, 2CH only.
For those who are very observant, yes, for now, we have installed the Oppo 95 tube board. I am using this PCB as a starting point and tweaking and voicing from there.
Please call if interested. The list is already growing!
Thanks!
Dan W.
-
Oh my Lord, I love tubes and upgraded caps! Tubes look so Christmany in the dark. :thumb:
-
Absolutely! This mod uses Modwright Custom capacitors, our custom Class A tube circuitry and as many as five tubes total - 2 in driver stage and three in external power supply.
The new power supply design uses tube voltage regulation (dual mono regulators) and tube rectification.
We are working hard on finalizing the mod and it will be available SOON!
Thanks,
Dan Wright
-
Do you think the tube mod will fit inside the stock (taller) Oppo unit, or are they going to be visible out the top like the existing 95 tube mod?
-
The tubes will most definitely be exposed through the lid of the player. This is both trademark and design necessity, in terms of heat.
I do plan on sticking with the 6SN7 tube and there may not be AS MUCH of the tube exposed, as there is a bit more room inside the unit, but they will be largely exposed.
The tubes in the power supply will be enclosed. This means that the rectifier choice will be limited to the 5AR4/GZ34, unless the lid has a hole punched or machined in it for use with different rectifier tubes, such as 5U4GB and 5V4GB. The other tubes will be '--EM7' family.
This is a VERY EXCITING project as I am ALREADY getting GREAT sound, and I have only installed the '95 tube mod board and new power supply. There are still another items to optimize and it is coming together quickly!
Thanks,
Dan W.
-
Dan, for my 105, I want my tubes to stick out as much as possible to make Ron Jeremy blush! :P
-
For my system, would look at a full solid state mod for HT and some music. I have a Modwright 83 SE that still sounds great, but has some miles on it. :D
Also have the Tube Oppo 95 for the audio only system, and I think it's great! Not in any hurry to upgrade it.
-
If I am right, then the 103 mod will be THE solution for SS fans and the 105 tube mod will suit the interests of those looking for true high-end audio via tube analog stage.
I will report back as soon as I get the first 103 prototype done and finalize the 105 mod.
I am a good way through the 105 and am expecting parts and proto PCB's early this coming week, for the 103.
Thanks!
Dan
-
Would you consider a linear PS for the 103? I've been very happy with your full SS mod with the 83SE (it also has the XLR and clock mod as well).
-
Dan,
Can you increase the height of the power supply so 5U4GB and 5V4GB rectifiers will fit? I want to use my NOS Tung-Sol 5U4GB rectifiers.
Thanks!
-
You probably already know this, but Dan cuts a hole on request so accommodate those tubes. I'm currently using a Bendix Radio 5V4G (date code 9/43) with outstanding results. Also have the Sylvania 5AR4 Fat Bottles that stick up slightly.
-
A hole is probably easier to roll tubes :D
-
I am looking at a linear PS for the 103.
I will also look into either punching the lids of existing PS enclosures or on our next order, have the lids punched by the machine shop.
Thanks
Dan
-
Already got some Bugle Boys, RCA JANs, and CBSs!
-
Progress Update!
I have a working prototype using four out of the eight DACs on the SABRE chip. It sounds fantastic via XLR and RCA, USB in via J. River Media and on all disc formats. The proto includes the new power supply design with tube rectifier and tube regulator tubes.
Next step is to incorporate the remaining four DACs in the tube circuit and in turn, allow for upgraded HP performance as well as standard playback performance.
Further upgrades to test in, include silver wire, Tantalum resistors and dialing in tube bias (operating point) of tube circuit for ideal synergy.
I am also going to examine the possibility of replacing the SMPS (Switched Mode Power Supply) with a linear supply of our own design. I already have a proto PCB built and assembled for the 103 PS and am working out the final details.
Just wanted everyone to know where we are at.
IF INTERESTED IN MODS - PLEASE CONTACT US TO BE ADDED TO THE LIST! IT IS GROWING LARGER EVERY DAY!
Thank you!
Dan W.
-
So all the standard functions still function after the mods? You can still stream music and use this as a dac?
-
Hi Dan,
Are you planning a solid state mod for the 105? I would definitely spring for one of those.
-
+1
-
Dan will offer a SS mod. We just have to wait our turn.
-
Hi, first of all, the tube mods and SS mods will NOT disable ANY functions of the player.
I have decided that the headphone section will remain stock. I may offer a headphone specific upgrade, but I am too concerned about creating TOO high of output levels and damaging headphones or ears! I did NOT find improvement by using these extra DACs in parallel with others for our tube stage.
Silver wire installed and WOW it sounds good! This is the 105 with tube mods that I am speaking of now!
My mod tech is going to work out the final mod board mounting and mechanical details over the weekend and the first unit will be complete next week. The list of those interested or waiting to order the 105 tube mods is long and growing!
I am also working on the 103 SS mods. I did NOT realize how much current the 5V supply draws, so I have had to order a bigger transformer for this and will be implementing updates to the SS mod design next week. What I do for the 103 SS mod will translate largely to the 105.
The 105 tube mods will be rolled out next week and the SS mods for 103 and 105 will follow next week.
Thanks!
Dan
-
Thanks for the update Dan.
I'm interested in the 105 SS mod. Will the silver wire and Tantalum resistor be used in the SS mod too?
-
Hi guys, not sure about Tantalum resistors in SS mod, but wherever there is wiring, it will be silver.
There is a reason that I chose silver wire for the tube mods. It is about tonal balance. The SS mods will depend on tonal balance also and without tubes, will be different.
Thanks,
Dan
-
Hi Dan, to break in the unit do you just play it 100+ hours or so, or use something like the (Purist Audio Design) System Enhancer (burn-in disk) ?
-
You could use a burn-in CD, or just play music through it. I just play music through my gear to break it in. Just put it on repeat and let it play 24/7, as long as it is connected to a preamp or amp, to have a load.
Thanks,
Dan

So, the NOS tubes I bought based on your 95 tube mods will not work?
-
Please re-read above.
The same drivers are used: 6SN7 and the same rectifier is used, 5AR4/GZ34. You may also use 5U4G or 5V4G and there are two additional tubes used in the new supply for voltage regulation. These are 15EM7 and suitable subs are 12EM7 and 13EM7.
The 6SN7 and 5AR4/GZ34 tubes from the 95 are the same.
Thank you,
Dan W.
-
Dan,
Will it be possible to get the 2-channel 105 tube mods AND the 105 SS mods for all other multi-channels? Price?
May be interested in the not yet completed 105 headphone circuit modification also.
[The previous status of imminent/pending Oppo 105 release with possible asyncrhonous DAC input is what kept me from going forward with LS100 DAC option some months ago...]

Hey Dan,
I could still then use my Shuguang CV181-Z Treasure tubes on the BPD-105.
Mike
-
I will answer for Dan. Yes. That tube is really a 6SN7 replacement. It isn't a true CV181.

I will answer for Dan. Yes. That tube is really a 6SN7 replacement. It isn't a true CV181.
Soon, we should start a tube rolling thread. :thumb:
-
There are several already. The thread for the Modwright transporter applies for the BDP-95 and 105 tube mods.
-
Hi guys, I had a chance to do a direct A/B with the same preamp, same cable between players and preamp and every other variable the same.
Oppo 95 tube mod with tube-rectified and SS rectified external power supply. Copper internal wiring.
Oppo 105 tube mod with tube-rectified and tube regulated external power supply, silver internal wiring and other bias and design updates to tube circuit, specific to Oppo 105.
I should point out that the Oppo 95 and 105 tube circuits are very similar. We changed critical resistors types and biased the circuit differently for the 105, to voice it properly with the new external supply. We also used ultra-pure silver wire in the 105 vs. copper wire in the 95. Lastly, we upgraded the power IEC to Furutech and stereo RCA's to Cardas.
The results:
I found that overall, the 105 was more open, resolving and produced a more natural presentation with a BIGGER soundstage and more holographic imaging. There was a greater sense of air with the 105. The 95 by comparison was just a bit warmer and darker sounding, with not as much depth.
They are both exceptional and the mod circuits are very similar, except for the external power supply. Both players use the same DAC. The 105 offers a headphone amp and digital inputs via optical, coax and USB, allowing it to act as a DAC - of course using our tube analog stage and taking full advantage of our mods!
The 105 is $1200 vs. $1K for the Oppo 95. Oppo REALLY took things to the next level with the 105! They used a bigger overall enclosure without a fan, to allow totally passive cooling. They also built an even more rigid and non-resonant enclosure and drive enclosure. Lastly, the internal linear digital and analog supplies are also more sophisticated in the 105!
In keeping with Oppo's own upping the ante, we designed a NEW external tube supply and redesigned our 95 mod to offer the best possible sound with the new supply and new Oppo!
In short, the 105 tube mod IS better than the 95! It is not a subtle difference and was quite audible!
Thank you and please contact us with any questions or to place an order and get on our list!
Sincerely,
Dan W.
-
Dan, can the power supply designed for the 105 be used with the 95? It sounds like it is a more refined power supply. Can you explain the major differences?
-
Hey Kids!
If you want to hear the ModWright Oppo BPD105, come by our room 4001 Flamingo Hotel at the 2013 THE Show in Las Vegas Jan 8-11! The Limoncello is coming along quite nicely as well.

Mike, I missed you last year as I went to RMAF. I will be there this year and can't wait to hear your new baby. The best Jeff Miller
-
Thanks Mike! NFS room is always an OASIS in the madness at CES and the Limoncello....oooh that stuff is dangerous :). I hope you guys have a great time!
I won't be exhibiting at CES this year, as we are going to Munich instead.
Please do check out the new Oppo 105 with tube mods at the NFS room!
RE the new supply for the 105, it IS backward compatible in the Oppo 95. The main difference is that the voltage regulation is handled by an all tube circuit, using a pair of 13EM7 regulator tubes. The previous supply handled voltage regulation with a SS FET design. I find that the tube regulated supply is MUCH more musical with a bigger soundstage!
Price for a new tube-regulated supply = $600.
Thank you,
Dan W.
-
Dan if you use the 105 tube power supply with the 95 does one have to do anything to the 95 cd player? Or is just plug in and play.
-
As the Oppo 95 tube mod user, I'd like to also add on Jeffy's question that, the new $600 tube regulated supply, would make the old PS 9.0 unit redundant, correct?
Thanks.
-
Klao, I would assume it is a direct drop in to replace the 9.0. You would just attached the umbilical cord to the new power supply.
-
The new supply will be a drop-in replacement for the PS 9.0. We will likely look at the option of upgrading existing PS 9.0's at a lower price.
Thanks,
Dan
-
The upgrade option for the PS 9.0 sounds like a winner.
Any news on the SS full channel mod for the 105?
-
Second that on the upgrade option.
-
Hi guys, no news on the SS mod for the Oppo 105 yet. I am working out details for the SS mod for the 103, to include a linear power supply and upgraded analog stages.
I am HOPING that the same LPS can be used for the 105, but I won't know until I complete the 103 LPS and determine space requirements and heat generated.
Tube mods being done right now, while I work out the SS mods details.
Thanks,
Dan

Dan, sounds like perhaps a 103 with SS and linear PS would be the way to go after all. What would the projected cost for this be, and how soon can we send you a 103 to get the mod?
-
I am projecting $500-$700 for the 103 mods. I will let everyone know when it is available. Please don't send a unit until then. We are taking orders for the 105 tube mods right now of course and they are stacking up fast. I am finalizing the 103 mods and will announce final pricing and availability when complete.
Thanks,

I am projecting $500-$700 for the 103 mods. I will let everyone know when it is available. Please don't send a unit until then. We are taking orders for the 105 tube mods right now of course and they are stacking up fast. I am finalizing the 103 mods and will announce final pricing and availability when complete.
Thanks,
Dan W.
Excellent. Please keep us posted.
Since I am going to use this unit for multi channel music, I think the 103 with full solid state mods is the way to go.
I am also keen to get my 95 tube power supply upgraded.
-
I will let you guys know when it is ready.
There are two major components to the 103 mods.
1) Linear power supply to replace SMPS stock.
2) Upgrade to 2CH and/or MCH analog circuits.
I will notify when complete.
Sincerely,
Dan W.

I'm interested in hearing more about the linear power supply for the 103. As to the analogue stage, I will take mine out and throw mine in the trash so no interest there (and obviously no need for the 15V from the LPSU). No point having it polluting the rest of the unit. (Hence no interest in the 105.) But what about the clocks in the 103 (there were 3 in the 93, not sure about the 103) - have you ever looked at upgrading these to, say, OXCO? (PM if preferred)

Hi, first of all, I have made progress this week on the LPS for the 103. I also learned, for those interested in this subject, that the 105 and 103 do used the same SMPS, but in the case of the 105, the SMPS does not supply +/-15V. As such, our LPS design for the 103 will be the same for the 105. We can simply omit the transformer and +/-15V supplies, focusing only on the 15V and 5V digital high-current supplies.
Instead of a single transformer, I have chosen to use three separate transformers for +5D, +15D and +/-15A supplies. I initially underestimated the current demands of both 5V and 15V digital supplies, but now have that worked out. I need to order two more transformers and work out the final high-current regulation circuit for the 5V supply and design the final PCB. Space and heat rejection are the biggest hurdles here. I know that it will fit, but I have to evaluate the heat rejection and how this is best accomplished to avoid over-heating the player. I already have this worked out conceptually, but still need to implement everything and test.
I am quite confident that this will make a NOTICEABLE difference in ALL aspects of the units' performance. SMPS's are notoriously noisy due to RF switching frequency. This noise will be present not only on the power trace, but also radiated inside the player. A LPS (Linear Power Supply) is transformer based and does not use any switching. It a much more expensive way to provide power, but is a better solution for audio. If Oppo built full LPS supplies for these players, their price would be QUITE a bit higher! It makes sense for DVD mfrs. to use SMPS's because of their cost, space savings and efficiency.
I plan to offer mods for the 103 in two forms:
1) LPS upgrade.
2) Analog stage upgrades, in the form of component upgrades and minor redesign, to improve sound.
The goal for the 103 upgrade is, of course, a high-value mod that will serve the needs of those who are using it ONLY for video and as audio transport. The other mod will be for those who use it for audio and music as a player.
Thank you, more to come!
Dan W.

^ Great info Dan. Thanks
-
Dan, will a 230V version of the LPSU be available?
-
Hi Dan:
Congratulations on the launch of the 105 mod.
Will the 105 play DSD files in the new protocol from a computer hard drive connected via USB? I know that J River supports DSD.
-
Hi Dan,
You had some ideas for a 103 mod. Has anyone expressed interest in a 103 Mod? If yes, what would the approximate cost be?
-
I am still working on a mod for the 103. Price for mods will start at $500.
Upgrade IEC to Furutech.
Upgrade op-amps and ideally eliminate output coupling caps.
Damping of chassis and drive.
Upgrade stock power supply.
OR
Replace SMPS (Switched Mode Power Supply) with LPS (Linear Power Supply) of our own design.
I am still working on the LPS and have just about finished it. Initial design underestimated current demands, so I have had to approach the design from a different angle. Parts will be in hand after the Christmas Holiday.
Thanks,
Dan W.
-
Hopefully (finger crossed and looking for 4 leaf clover) the LPS of the 103 will fit inside the 105!
-
Regarding the mod for the 103, what Furutech inlet will be offered (FI-09 or FI-10, Gold or Rhodium) and what op-amp (Burson)?
You indicated the 4 option upgrade (IEC inlet, op-amps, damping and upgrade to stock PS) OR the LPS. Which would provide more benefit? I'm most concerned with audio performance as the video is already satisfying to me.
-
Dan are you going to have the Bybee rails available for the tubed Oppo 105 and if so when and how much?
-

A guy I can appreciate! :thumb:
-
Hi, we do offer a single Bybee rail installed in the critical DAC voltage supply for the stereo DAC. Cost add = $225. NICE IMPROVEMENT! Cleaning up power to DAC lowers jitter levels and further reduces jitter-induced digital edge/glare.
Thanks!
Dan
-
Hi. Any updates?
-
Bybee rails successfully installed in 105 for both 2CH and MCH applications with great success.
LPS design finalized - i.e. schematic tested as working. Final PCB layout underway.
I have confirmed that dimensions of (2) > 50VA power transformers for LPS - one for digital, one for analog, will fit dimensionally in both 105 and 103.
Tube mods are going out the door every week and once the LPS supply design is complete, the other upgrades to the 103 are already in mind and will be evaluated separately, in addition to LPS.
I may implement them first, with just SMPS in place and then evaluate additional improvement of LPS with other upgrades.
Pricing and results to follow.
Thanks guys!
Dan
-
Hi Dan, thanks for updates. Just a passing thought, could you build a Modwright labeled "cost almost no object" Oppo based player? I mean your own chassis with no constraints? Similar to what Theta or Arye has done?
-
Hi, it could be done, but the cost would be HIGH! To be honest, it makes more sense to modify the players as we do and offer the SAME level of performance at a significant cost savings. There is a reason that Ayre charges $10K for their Blu-Ray player, based on an earlier Oppo model. Granted, they redesigned the power supply and much of the player, including the enclosure of course. Other companies have take these units and made little changes other than to dress them in their own chassis and charge a LOT for them. I don't believe in that model.
The only justification I could see for doing that, would be if it gave us more leeway to design a BETTER sounding product. I honestly don't believe that to be the case. As a result, I plan to make the stock units as GOOD as they can be, in their own enclosures, with our modifications.
Thanks!
Dan
-
I agree that Dan's approach makes much more sense. By the time you get back a newly designed enclosure and work on all the changes, the model is probably much closer to being replaced by a new one that just modding it. The $10k Ayre I believe is now based on an old model.
-
Dan, have you advanced your plans for offering a power supply upgrade to us MW BDP-95 owners?
And thanks for taking the time to hang out with us mortals on the board. We really appreciate it.
-
Hi, the LPS that I am working on, will be compatible with the BDP 93 and BDP 95. The new tube supply is ALSO compatible with the BDP 95 tube mods as well as our other Sony tube mods.
Thanks,
Dan
-
Thanks Dan. I was referring to the tube mod PS which you said could be upgraded, including allowing for taller tubes.
-
Dan, have you tried connecting the BDP-105 directly into a power amplifier using the Oppo's digital volume control? I've read good and bad things about this and would like to hear your thoughts. The Oppo would be my only source, so eliminating a preamp and putting extra money into a new amp would be a big plus.
Thanks for your time.
-
I have and results are not good. I would recommend using a preamp.

MellowVelo,
Yes there is a contingent of audiophiles who make this argument or argue for passive preamps of one sort or another. But opinions, systems and audio preferences differ. This topic is always a big can of worms but I am interested in hearing Dan's take. For me, an active pre is key to getting the sound I want, though it isn't always cheap to get an active pre with the level of detail a passive or no pre can provide. Actives IME have dynamics and an oomph to them that the passives I have tried can't match.

Very true. I am keeping an active pre, and I only am using it for my 105 and cable.
-
OK, a couple of things:
First of all, digital attenuators decrease volume by dropping bits. This is a 32-bit DAC, so you would not expect much music resolution to be lost, but there is always going to be some IMHO.
The other issue has to do with impedance matching and current buffering, whenever you are talking about passive attenuators in lieu of active preamps. My feeling is that the BEST and CLEANEST passive attenuator will NEVER sound better than a GOOD active gain stage. Admittedly, a poor active gain stage will add unwanted noise, distortion, etc. A good active gain stage, my preference is for tubes, will give you good impedance matching and current buffering, which seems to 'flesh out' the sound, as compared to a passive attenuator.
Just my $0.02!
Thanks,
Dan W.

Dan, what is the status of the 105 SS mod? I recently picked up a 105, and I must say, it is VERY good stock. In fact, it is so good, that after comparing the multi channel out to my Modwright Oppo BD83SE, went ahead and sold the 83. I compared the multi channel out from the 95 to the 105, and the 105 does sound better, no question.
I have the Modwright BDP-95 tube unit for my two channel playback, and absolutely love it. It really shines with NOS Sylvaina 5692 tubes, and a Bendix 5V4 rectifier. So, I know the tube mod makes a huge difference. However, I wonder if the 105 has gotten to the point that the SS mod may not be worth the cost of admission? I can see where the 103 would be a good candidate for the upgrade, but the 105 already sounds like it is as good as it can be via the SS out.
Lastly, what is the difference with the 105 tube PS when connected to a modded 95?

I am sure Oppo had some price restraints when designing their products, no matter how good they sound/look. Modding just takes to another level.
-
I'm not one to blindly believe that a mod will "always" improve the sound. Oppo did a bang up job on this audio board, and it's an improvement over the 95 stock on multi channel, no question. Their web site indicates they had some outside help with the audio boards this go around, and it shows sonically. Just the fact that they split out the audio boards I think has caused some improvement.
If one is going after tube sonics, then yes, then the mod takes it to another level in the improvement arena. I'm not so sure about the solid state mods causing all that much of an improvement (with this player), especially one that essentially doubles the price of the player. The mods did help out the older players, such as the 83.
As stated earlier, as much as I enjoyed the modded 83, the stock 105 is even better (than the modified 83) via the analog out (2 or multi channel).
As Papa Pass says: "Make it as simple as possible, but no simpler than it needs to be".
-
First of all, you are right, the stock 105 is very good! Our tube mods make it significantly better, by replacing all of the op-amps and Stereo SS circuitry with our own tube analog stage and its own dedicated supply. We also improve the stock supplies that power the DACs.
In the case of the 103, while the design is good, the SMPS (Switched Mode Power Supply) is very lacking and the parts quality is poor. In the case of the 105, they used GOOD op-amps and decoupling caps as well as providing a good linear, regulated audio power supply.
The biggest part of the SS mod for both the 103 and 105, will be to replace the SMPS with a linear supply of our own design. In the case of the 105, the SMPS still powers all video circuitry as well as drive, servo, focus and voltage relating to the CD drive itself. I exptect SIGNIFICANT improvement in this regard for the 103, as the SMPS powers the ENTIRE unit. In the case of the 105, it will lower jitter levels by improving power to the driver and focus/servo circuits. It may also power the digital input board - have not verified this yet.
One of the reasons that we have not produced a SS mod for the 105 is, quite frankly, because I agree with you. Good parts were used and a good supply for audio was also used. I first want to complete the LPS for both units and assess the advantages of this ALONE in the 105. From there, I will see what else we can do for a SS mod.
It may turn out, that for the SS mod, the 103 is the better choice!
Thanks,
Dan
-
Thanks Dan, for an honest and straight answer. I will be very curious to see how you go with the 105.
As for the 95, can you explain what sonic benefit would be gained by the upgraded tube PS? I can tell you that the 95 with the existing PS sounds fantastic with the Bendix 5V4 rectifier and 5692 tubes!
-
Hi, the advantage to the new tube supply, for the Oppo 95, is the use of tube voltage regulators instead of SS voltage regulators. I find that the soundstage is MUCH broader and deeper and the presentation more 3-Dimensional. That is the biggest difference in the new power supply and it really DOES make a big difference.
Thanks,
Dan

You misunderstand me. Blindly? Hardly. After much thought and design, mods can be very, very beneficial. Improving caps, power supplies as an example. And I am not just talking about Oppo.
-
Dan, just saw your updated 105 website. Your caps make me all warm and fuzzy inside, in a good way! :thumb:

The statement was in strict reference to the BDP 105, nothing more. Do not read into it.
The 105 is already so good, it is questionable if any mod (that is reasonably enough priced) would improve performance enough to justify the cost and effort. That is what was meant by "blindly" accepting a mod (in the SS arena) wold help with the 105.
For the tube mod, yes, no question.

As a university BA graduate, I tend to read into things. I can respect your point of view in regards to not knowing about the benefits of mods, in regrades to cost vs. benefit factors. IMHO, some companies listen more to their bean counters and not to their designers.

If you could share the thought process of going specifically w/a pair of 13EM7 for the new PS, that would be great!
W/all the tube rollers around here, you sure came up w/a pretty obscure valve as far as NOS choices go. Although a much respected sounding dual triode.
Besides choosing the model of tube what if any tube rolling did you do?
-
To be honest, I have used the 6EM7 in our LS 36.5 'DM' with good results. I contacted a tube supplier that I buy from in quantity and he said that he had SOME 6EM7's, but could access a large number of 13EM7's. The 6EM7 uses a 6V filement, the 13EM7 uses a 12-13V filament and the 15EM7 uses a 15V filament. I bought a large quantity of the 13EM7's, to insure that I would have a good stock with which to supply our design.
That is why.
Thanks,
Dan W.

Dan,
Do we need to order new tube power supply for Oppo 95 or we can send in our old power supply to upgrade
What is the price if we send in the old one for upgrade?
-
You can send in the old supply to have it upgraded, for $500 or purchase a new supply for $600. The upgrade includes totally gutting the existing supply and installing all new circuitry, including an additional transformer for the regulator tubes.
It IS a very nice upgrade!
Thanks,
Dan

Makes $en$e!
Many a fine piece of audio gear has bitten the dust because of lack of parts.
[if my badd memory serves me right Oppo ceased making an SE cause of lack of chips]
I brought up a large quantity too, JJ... two pr each of a "GM Delco" [June 1960] (made for a '61 GM car radio/blows the mind!) & a "Sylvania" [fr: the '50's/possible for a TV!] (just fell hard for the Syl 6SN7 "Chrome-Top").
Just missED the delivery of my new PS tonight; I'm off tomorrow so should be able too grab it!
No reply requirED nor requestED.

Dan,

If you send in a PS 9.5 you'll pay for shipping both ways.
If you buy the new PS 2B#later [maybe 9.9] you'll pay for shipping one way.
You may want too check shipping $$$ 1st & est. in your personal 'cost' of MWI mod'd 95 downtime [w/o any PS], IMO, YMMV.
-
Maybe it is better to sell my tube mod Oppo 95 and then get Oppo 105 tube mod.
-
I did not want to be without the power supply , and was able to sell my old power supply after receiving the new one.
I can say this about the new power, it made a significant difference in my oppo se 83 from the single tube to the 3 tube power supply. The old power supply did not like 274 tubes, this new one is fine with them. I have not researched the regulators due to my opinion if the they are stable what could a new vintage tube do. The noticable thing to me was a gain difference between the tube power supplies, I realize there should not be one as this is power, but maybe the tube regulators do something to the power to signify a gain change.
-
... the 13EM7 uses a 12-13V filament and the 15EM7 uses a 15V filament...
Dan,
Do you then believe/think, as many do, that the 15EM7 is indeed a sub for the 13EM7?
Maybe it is better to sell my tube mod Oppo 95 and then get Oppo 105 tube mod.
teetee,
Just too be clear, I'm not saying sell your 95 instead of just buying a new PS.
However, if you can take the hit, the 105 w/o the fan & w/digital inputs does two-up the old model.
If I wasn't going too be dead in a yr... I'd do it myself, ha, ha!!
I did not want to be without the power supply , and was able to sell my old power supply after receiving the new one...

Dan didn't change the DAC's in the 95; nor the 105.
The Oppo 95 is "powered by two ESS Sabre32 Reference Digital-to-Analog Converters"
&
the Oppo 105 is "powered by two ESS Sabre32 Reference Digital-to-Analog Converters".
The MWI Tube Mod only modifies the analog output. Not the D/A conversion.

I sold the power supply to a gentleman in utah I believe.
The 274 I have had laying around over the years and wanted to try since they were western electrics which i aquired basically free while working for at&t.
The 274 is different construction and just looks prettier lit up lol.
I could hear a gain difference between the two power supplies using same tube in each.
I dont get into describing sound to much but I do not have the critical ears for that.
I do sometimes hear differences sometimes and just give my brief findings.
I just enjoy the hobby, I listen to metal most of the time, maybe few other things such as females for voice testing, but I like it loud so my equipment must be able to perform at high levels which isn't the best for critical listening.

Dan,
How would you quantify the performance improvement that upgrading to the new power supply with the Modwright 95 provide?
What sound characteristics differences should one expect?

I'd like to hear about this too. I can imagine it would be a tricky issue for Dan to talk about. But... yeah, I would want this $3500 player/DAC (used as a DAC) to sound substantially better than my $1500 DAC. I don't spin many audio discs.
Is there an approximate total height for the unit with, say, a tallish tube like a Ken Rad sticking out the top?? thanks

I test a lot of cds for sound even with my horrible hearing.
I use as a reference metal cd's:
In this moment - blood
evanescence - new self titled
firewind-live premonition
all that remains - overcome
pantera-far beyond the great southern cowboys vulgar hits
judas priest- demolition
female vocals i use the following bands:
faith hill
wilson philips
heart
rock cds i use:
nickleback
guns and roses
thin lizzy
iced earth
iron maiden
dokken

Our LS 100 preamp retails for $3500. The DAC upgrade is $1600. I just wanted to clarify this. It is an exceptional sounding tube DAC.
I do not see how there could actually be a change in gain wi the new supply, but often cleaner or better sound can be perceived this way, if the noise floor is lower and soundstage improved.
I have not used the 274B tube.
Thanks,
Dan

Hi Dan,
No pressure, but any news on lps? Thanks!
-
I have installed it in the 103 and have been evaluating it against the 105, first with no other mods and then with the rest of the mods that I had planned. I have yet to put the SMPS back in and see what the difference is. These comparisons have all been done using the player strictly as a 2CH player, and not as a transport.
I plan to finalize this testing by tomorrow, and will also compare the 103 w/LPS to a stock 105.
I will be installing the LPS in a 105 today also and will have the results of this testing by tomorrow also.
I will share all of my results once I have finalized all testing.
Sincerely,
Dan W.

The Results:
1) The LPS is a NO GO in the 103. It runs too hot and the sonic benefits were simply not what I expected. The enclosure is sealed, so there is no good way to reject heat. Mr. Lee has designed a LPS that may be used in the unit. I have tested and installed a 'Lee' LPS and it is a good design. However, if you add Lee's LPS to a unit that we have modified, it WILL void our warranty. I simply feel that the LPS generates too much heat for the 103.
2) The LPS in the 105 I have looked at extensively and decided the following:
A) It ONLY provides 5V supply to the processor board and +15V to the drive.
B) Despite the fact that the unit is passively ventilated, it already runs warm and I am concerned about heat.
C) The LPS would put two transformers right below the MCH audio board and I would be concerned about EMI and other noise contributions.
D) Ultimately, due to my findings with the 103, I have decided that the LPS for the 105 is simply not going to provide a worthwhile benefit and I am not willing to add the risk of future reliability issues, due to excess heat.
3) I listened to the 103 with LPS and SMPS and found VERY little difference. I also measured the digital out signal and found no measurable difference.
4) The 103 stock is NOT as good as the 105 stock! The 105 is MUCH BETTER!
5) The modified 103 (without LPS), but with upgrades to shielding, damping, parts upgrades in analog stage and power supply is much better and closer to the performance of the stock 105, but I would have to give the edge to the stock 105.
I have decided that we will offer a $500 mod for the 103 that will include the following (2CH only):
Power Supply upgrades to stock SMPS.
Chassis damping and shielding.
Upgrades to analog stage (eliminate all coupling caps).
Upgrade IEC to Furutech Cryo-treated IEC.
I am still tweaking a couple of things, but I first had to make a decision about the LPS. I have not compared the two units strictly as transports, but would expect very similar results. In both units, the digital out circuit, on the processor board, is powered by the SMPS. This includes audio coax and optical out, as well as HDMI for video. Both 105 and 103 use the same processor board and video chipset, powered by the same SMPS (Power Supply) design.
Our mods for the 103 are intended to improve its use as a player primarily. The damping, shielding and power supply upgrades will provide some improvement to its use as a transport and for video.
Thanks guys, it has been a bit of a journey here and the results of the LPS surprised me, but I refuse to offer an upgrade that I do not feel is worthwhile and also that I am not confident of its ultimate reliability.
Sincerely,
Dan W.
-
Dan, thanks so much for your extensive report. I really admire your honesty and transparency. Do you still plan to offer some sort of SS mod for the 105?
-
Thank you. I would rather be honest, than offer a mod that I do not feel will be reliable and that I do not feel justifies its cost!
I am not sure what we will do about a SS mod for the 105. To be honest, it is a VERY good unit to begin with. There are some things that can be done, damping, PS improvements, possibly remove coupling caps if this is feasible and some other things. I will see what can be done. My first intent was to implement the tube mod in the 105 and bypass all op-amps and SS circuitry because I KNOW how good this sounds.
It was my intent to offer a SS mod for the 103 instead. I will look into the 105 now with a SS mod in mind and see what makes sense.
Thank you,
Dan Wright
-
^ I look forward to finding out what you learn about the 105. Can Bybee rails be installed in the 105?
-
Bybee rails can be added in the 105, yes. So can the Audio Magic Pulse Gen ZX.
Thanks,
Dan
-
Have you ever tried any of the varieties of WA Quantum Chips in an Oppo?
-
No, but the Audio Magic Pulse Gen uses Quantum technology I am farily certain.
Dan
-
How about those little audio fans to combat the LPS heat?
-
No fans....sorry.
Dan
-
No fans....sorry.
Dan
LOL. :green: :lol:
-
How about the transport of the 105? Do all Oppos use the same transport mechanism?
-
Yes they do.
Thanks,
Dan
-
Yes they do.
Thanks,
Dan
Sad to hear. I borrowed a Marantz BDP while my 105 was being modded, and man is it a lot quieter when opening/closing than my old 95.
-
I now have about 30 hours of break in on my Modright Oppo 105. I can tell you that if it did not improve any more, the sound I am getting now is much better than my old Modright Oppo 95. It is much more organic in the mids. The dynamics are startling. The noise floor is much quieter and what is most interesting is that the pace and rhythm is much better. You get much more involved in the music and the pace is much faster. The soundstage is bigger and more defined. It is much more transparent but also at the same time more musical. This folks is hard to do and the Modright 105 does it in spades. This player is killer and can compare to digital in the 40,000.00 price range. I just can not believe it boy Dan can hear. I'm like a little kid thanks Dan.

Were you able to do side by side tests or is this from memory?
-
Of course I still own the 95. By the way do you want to buy it?
-
No thanks. Already have one of my own.
-
Dan, will you be demoing your modded 105 at Axpona in March in Chicago? If so, I'll stop by for a listen.
-
Just got my Modwright Oppo 105. Glorious, awesome and then some. Dan has outdid himself (again). And I was coming from a $18,000 Wadia. The human voice through my 105 gives me goosebumps. I will go in more detail when I listen more and it breaks into my system (Venture speakers, Hegel H30 amp, Concert Fidelity preamp)
-
Hoping someone can put up a series of nice detailed photos soon too. :)

Talk2me, I think the MSB stack at 50,000.00 may be better than Dan's new player, but I'm not sure. I would have to have both to compare. That is the only player that can compete which is amazing and especially the price. I still cannot believe how much better the 105 is. This folks is very close now to the best analog.

Wait a tic. Have you tried the 105 power supply with the 95?
My guess is that the 95 would sound almost the same (to the point of being difficult to tell apart) with the upgraded PS. The reason I say that is because when I was fortunate enough to obtain a Bendix Radio 5V4G rectifier tube with Sylvania 5692 tube combination, the 95 took a big step up in performance.
Dan is offering the 105 power supply as an upgrade for 95 owners as a 600.00 option. May be well worth it.
-
What's the approximate total height with tubes in? Thanks.
-
What's the approximate total height wi :wink:th tubes in? Thanks.
The 105+ 2 inches. :wink: Also depends on what tubes you use.

I am using a pair of 6F8Gs in my 95 and it is at least 3-4 inches.
-
lol on the inches

Well, okay. That helps. Thanks.
-
Well, okay. That helps. Thanks.
Really? Can't go to the Oppo website?
-
I wasn't being sarcastic. I wanted to know how far the tubes stick out of the top of the 105. I already own one so I can simply add 2 inches with my mad math skills (and a ruler).
sorry. i guess
-
I added socket savers to raise mine due to fat bottle 6sn7's, would barely fit in top, but with the savers now no issues.
-
The height of the Oppo 105 is 4 3/4" from the base to the top of the front faceplate. The stock EH 6SN7 adds aprox. 2" +/-
Using TSRP 6F8G tube (w/ adapter) adds aprox. 4 1/2" +/-
YMMV depending on what tubes you use so these are approximate heights.

great. thanks.
So it's really just the base (of the tubes) that's below the top surface then. That works. Just thinking about cabinetry.

It would be great if someone would quantify the performance improvements in several use cases involving the 95 and 105.
Such as:
1. ModWright 95 vs. Oppo 105
2. ModWright 95, new PS vs. Oppo 105
3. ModWright 95 vs. ModWright 105
4. ModeWright 95, new PS vs. ModWright 105
Current owner of a ModWright 95 with ByBee rail and AudioMagic and I'm trying to determine what type of performance delta I'm looking at versus the 105.
Thanks!
-
The only person that is going to be able to answer that one honestly would be Dan himself.

If you read "all" of Dan's posts on 95, 103, & 105 [since the 105 has been released & Dan got both units in the 100 series] threads you will get an answer too most of your Q's.
I never saw a #4 tho!
-
I think if you read about the comparison of the 103 to the 105 both modded and unmodded you will note the 105 is the better of the two. Since the 105 comes with the new power supply and Modwright umbilical it is pretty safe to assume that the modified 105 is better than a 95 with the new power supply. However, if you want a step up with your fully modified 95, then the new power supply added to your unit (95) is the way to go without having to purchase a new player (105) and have it modified. In the end costing you $500 for the new PS versus over $3300 for new player and modifications. However since we, as audiophiles, always quest more of the holy grail of sound perhaps the need for new and better sound will only be satisfied by new and better equipment. :thumb:

I don't want to take this off topic, but I think it applies. I think the determining factor for me on whether to go this route or not would come down to the performance of the DAC. I have no doubt the ModWright mods will squeeze every ounce of potential out of the 105, but you are still locked into the Oppo implementation of a Sabre DAC. I don't see the point of modding this unit if I'm using it only as a transport. This is designed to be used as a transport/DAC and also a stand-alone DAC for some other transport, i.e. a PC/Mac/other.
We all know that there is much more to a DAC than the chip. The Sabre is all the rage, but I've heard lousy Sabre based DACs (I know, the Sabre is sooo 2012! :roll:)
The problem is I don't really understand what really goes into a good DAC, so to me it might as well be magic. Every really good DAC out there has a specific approach to create their magic - upsampling, NOS, expensive opamps, no opamps, simple, complex, mystery chips, etc. You only have to go over to 6moons to find enough detailed explanations to boggle anyone's mind. Every reviewed DAC will tell you in excruciating detail what their unique approach is. Yet I have found no info concerning the Oppo approach, only that it's that "state of the art" Sabre 9018. If anyone can point me to any info, please do.
So for me it comes down to, does the Oppo DAC rival something like a Lampizator, Metrum Hex, Bryston's new DAC, Eximus, ModWright's own LS100 (which I've heard great things about), etc, etc... I don't know, the DACs ranging from $1,500 - $5000 let's say. Where does this box fall on that scale?
I'm sorely tempted because this is a spectacular all around machine, and with the mods it could be world class - IF - the DAC is equal to the task.

Yes indeed. And my ears tell me my ModWright 105 is one of the best, if not the best, source units I have heard in my system. :thumb:

talk2me,
have you try to use the internal DAC of 105 hook up as USB DAC for computer or any other digital sources. By any chance you can compare 105's DAC to any DAC out there?
-

There is a recent review of the 105 at everythingaudio.net that did that.

thanks Phil A and talk2me for the information.

Well, I can compare the Oppo and Wyred4Sound DAC-2 as DAC/Preamps. It would be cleaner to compare them with the same preamp... but I don't have one (yet).
So, as a DAC/preamp... the Oppo crushes the W4S. I have only 80-ish hours on it. The soundstage is much deeper and a bit wider on the Oppo vs. the W4S. It's also smoother and more musical. The bass is probably the biggest change in that the Oppo goes much lower and gives more apparent bass. It's freaking-awesome as a DAC through USB from my Mac Mini and Audirvana+ (integer mode). It also sounds nice playing off a thumb drive... but I think it's a little flat compared to USB. I have not tried any other DAC connection.
My amp is a Pass Labs X250 and speakers are Salk HT3 with RAAL tweeter.
Of course my experience is with a STOCK Oppo BDP-105. Hard to imagine Dan's hot-rodded version but maybe in a couple months I'll get to hear it for myself.
-
I can compare using my ART modded Squeezebox duet into the OPPO coaxial input , Bel canto DAC 3 spdif input or Bolder modded Eastern Electric DAC. With The Bel Canto, it is close and just the matter of an altered presentation. The Oppo is more extended in both frequency extremes and airier sounding. It also sounds more detailed. The Bel canto is more organic and has a more liquid midrange. The modded Eastern Electric DAC with the Pavane tube is significantly better on my rig. Here I have all the detail along with the organic liquid mids I crave. All of these comparisons are using standard rez FLAC files streamed to the Duet. My amp is a PrimaLuna Dialogue one with cryo'd NOS signal tubes and Svetlana winged C EL34. Speakers are ACI Sapphire XL and cabling is WyWires and Shunyata. The EE uses Sabre DACs, so I can see Dan's rebuilt output stage potentially working wonders on the sound vis a vis the stock BDP 105.
Further, playing hi-rez through the Oppo (both SACD and streaming) is very good indeed, though I haven't used the USB connection yet.
Hope this helps....

Thanks, this does help!

Don't buy an 105 too use as a transport, buy a 103.
I believe Dan was working on mod'ing the 103 into a transport only, don't know if he's continuing in that direction tho.
-
Thank you for the report ajayrav and ckunstadt
That helps what i am going to do with my Modwright tube OPP0 95, it will be up for sale.
Anyone interested?

1) The LPS is a NO GO in the 103. It runs too hot and the sonic benefits were simply not what I expected. The enclosure is sealed, so there is no good way to reject heat.

Interesting. I have a 'Lee' LPSU in my 103 and it doesn't even get warm after a week of solid running/burn-in, let alone hot. (Although I have removed the analogue section entirely and so I'm not drawing on the 15V (and have a little extra venting due to the holes in the back fascia where the analogue connections were).)
4) The 103 stock is NOT as good as the 105 stock! The 105 is MUCH BETTER!
When run as a digital-only transport or analogue out? I believe both models share the same main board and same transport. Is this incorrect?
-

From Mr. Wright:
Recommended Tube Upgrades for the Oppo BDP-95 Mod:
•Output Tube: Sophia Electric 6SN7 – Galen Carol Audio
•Rectifier Tube: Mullard, Amperex or Phillips ‘GZ34’
Fr: BIG old me:
•Output Tube: NOS Sylvania "Chrome Top" 6SN7('s)
•Rectifier Tube: NOS Holland GZ34 (although I'm a fan of the black base for the $$$ over the metal base & many others prefer British valves [see above])
1st just listen w/the tubes that come w/the mod.
Enjoy & then start the craziness!!!

How long is the break-in of Modwright 105? When I had my 95 (not Modwright modded), the break-in was up north of 500 hours. I'm now at a point where I cannot stand another long break-in (new speakers, dac, power receptacle and a powercord, none at the same time!) . If Modwright 105 is worth it though, I will still bite my lips and go through with it, but I'd like this piece of info before hand.
Thanks in advance.
-
500 hours? That seems like a very long period of time. Why do you think it took that long? I don't think my 95 took more than 50 hours, at most.

If I said it took a long time to break in the 95 that is true. The new 105 sounds great out of the box and I am breaking it in as I listen. When I get 100 or more hours on it I will report back. What ever the reason is the new mod sounds way better out of the gate than the 95 did when new.

if i were to get a modwright bdp-105, where is a good place to start with tubes?
also i'm not sure if i missed it, are there any pictures available of the modwright bdp-105 with the external ps?
One irritating thing I learned after I started buying and trying tubes, is that, for the MOST part, you get what you pay for. Many many audiophiles have sampled hundreds of tubes - especially the 6sn7 series - and have scored them, ranked them, written about them, probably painted pictures of them, etc. I read lots of stuff about which tubes would sound best on my Woo Audio WA22. Even with everyone else's experience, I thought that MY system would be different in some way that would make it necessary for me to try some middle-ranked (less popular) tubes in order to find the perfect match. Well... after spending $1500 on tubes, I can tell you that for 6sn7 series tubes, Tung Sol Black Glass Round Plates, Sylvania Bad Boys, Ken Rads, Raytheons, maybe National Union, all sound top-notch. Different, but all very good. And they range from about $100 to $500 per pair. Unless you're really lucky, you won't find tubes that sound as good as these for $30. I kept trying and failing.
The most over-rated tube (I think) is the RCA gray glass. I hate it and they can be very expensive. I have another pair of cheap RCAs that sound small and scratchy.
I think my WA22 came with a pair of super-cheap GE tubes. They are terrible. I don't think I've read anything good about GE tubes. I wouldn't waste money there.
Another thing I learned was just because a tube looks (and reads) to be very similar to a high-dollar popular tube, it doesn't mean it will sound 'almost' as good. A true Sylvania Bad Boy has three hole in the plates. They sound incredibly smooth and detailed in the upper-end and have a really nice mid-range. The "same" tube with 2 holes in the plates sounds fine but not nearly as smooth or detailed. These are sometimes sold as "Bad Boys" but they are not, really.
Another general note: I think most inexpensive tubes, and a lot of pricey ones, tend to be light in the bass. I might recommend finding a counter to that signature and making your first NOS tube purchase some Ken Rads (black or clear glass doesn't matter ((that's what I've read - haven't tried black glass)). You can decide from there if you really require that much bottom end or if you can afford to lose a little for something with a more pronounced midrange or something - like some Sylvania 5962 Brown Base.
I have not dabbled in the current production tubes other than $15 Tung Sols. I can't say if $15 Sylvania Chrome domes sound better than the popular Chinese tubes. Many seem to think so.
Anyway. Hope that helps a little without being too confusing. Have a blast! I've brought some of my rectifier tubes into work for a photo-shoot and people can't get over how cool and crazy they look. I tell them I can't get over how we don't have current production tubes that sound nearly as good as tubes that are 70 years old!!
Buy a plastic camera case to hold all your new tubes!

Thanks. I am familiar with jwm posts on A'gon. I myself didn't believe the 95 long break-in until I tried it myself. Although the final sound was quite acceptable the long break-in was one of the worst I ever experienced. :( It was last year and with 105 on the horizon then, I didn't keep the 95 very long. So...now I'm thinking either 1) buy a 105, try for awhile, send to Modwright - 2 possible break-in, or 2) keep the faith, have Oppo send a 105 to Modwright direct. Currently running Metrum Octave. Will Modwright 105 crash the Metrum as a standalone dac?

Just to make sure, yours is Modwright 105 and not just stock 105? Thanks for the info. I'll be following your findings for sure. :)

Is there any benefit to upgrading the clocks/oscillators at the same time as the other mods, or do the power supply mods make that not worthwhile?

KZHTOO, you will not be disappointed in the Tube Modright modded 105. I would have Oppo sent the unit right to Dan and also have the Bybee rails installed. This unit will delight you right out of the box. This for whatever reason was not the case with the 95. This unit comes so close to the best in analog plus it has a USB input to act as a dac for high rez. music.

+1. The 105 by Modwright w/music rails is state of the art.

can the oppo 105 be hooked up direct to the amp

Yes, it has volume control capability on the remote.
-
FYI. I have spoken to someone on the alpha team that now has DSD files playing through the Oppo USB input (pre-beta firmware). :) So it's close.
-
Maybe a dumb question, but does the USB input on these also act as an output? Thinking on the ability to use this player also as a transport for ripping audio/video files?

Thank you. This is very encouraging. Have you tried SPDIF input on your 105?

Is there any benefit to upgrading the clocks/oscillators at the same time as the other mods, or do the power supply mods make that not worthwhile?

I remember reading that post from Dan and being pretty bummed. Since then, I have purchased a ModWright LS100 (preamp) and with my STOCK oppo 105, it sounds inarguably better with the preamp. It's the only preamp I own... but I would GUESS that most mid-level preamps would be superior to no preamp. The volume control alone made it worth the hassle (for me) but the dynamics are also much much better. I don't have immediate plans to have my 105 modded, but I am thinking about it. I want to read more responses / reviews.

Hi Ted, do you know if it's going to be possible to play DSD files from a USB flash drive?

Could someone please check out how the new three tube PS sounds on a Modwright Oppo 95. Compared to the 105 with the same tubes and PS or just compared to the one tube PS in the 95. I'm strapped for cash and could probably spring for the $600.00\$500.00 upgrade to my 95 if its worth it. Thanks. :?

Please see my new post concerning this.

Thanks Randy. Sounds like the PS 9.9 is a worthwhile upgrade. I'll be calling Kristin on Monday. :lol: Would still like to hear from someone who actually owns the Modwright 105 and the 95 comparing the two with the new three tube PS.
-
PS 9.0 is the correct term. :wink:
-
Actually, Dan is calling the new PS 9.9!
-
Actually, Dan is calling the new PS 9.9!
Then my bad, and I will have to ask Dan why my 1 week old face plate reads 9.0 :x
-
You will need to look at the back of the Power supply. The back of the unit should have a 9.9 on it. Even my new one says 9.0 on the front. 9.9 just represents the upgrade. Think of it like a car. The Corvette has been around for a number of years and is now I believe a C7 model but it is still called a Corvette, not C7. And when changes are made each year to the C7 model they do not call it C7.1 or c7.2 for each subsequent year. It is still a Corvette C7, but you still know the difference on the inside.
Randy
-
For those of you who have the 9.9 PS, what tall/wide rectifiers are you using? I am getting the 9.9 with top hole cut out to fit a tall tube. I think I may get the widest opening since I want to use either an EML 5U4G or a 596 which requires adapter wires.
-
Is there any benefit to upgrading the clocks/oscillators at the same time as the other mods, or do the power supply mods make that not worthwhile?
Bump (again)
Most alternative modders also change out one or more of the clocks, and I'm trying to put that into perspective.
-
Why don't you call Modwright and ask them the question directly? Dan doesn't always have the time to monitor the forums.
-
To clarify the PS 9.0 9.9 issues:
The model '9.0' will stand. There will be a label on the back of the unit to indicate if it is a 9.9 revision.
Thank you.
Dan W.
-
In reply to the query about clock upgrades:
We did replace clocks in earlier Oppo models and I found that the clocking of the Sabre chip is unique and was more often than not, problematic rather than beneficial. It is for this reason that I have left it alone.
The SABRE DAC chip has a dedicated clock/oscillator RIGHT at each DAC and I believe that its jitter levels are EXCEPTIONALLY low to begin with. I do not hear the characteristic glare from the Oppo 105 that would indicate to me that Jitter is an issue.
Thanks,
Dan

Are you certain the EML can be used in the 9.9? I was using one in the 9.0 for the Oppo and it blew fuses. I kept on using it because I had no other use for it and it sounded great. It died a few months later. Dan had warned me that it could be hard on the tube. If the mod allows that tube, that would be great and added incentive for me personally.
-
I asked Dan and he said 5U4Gs can be used in the 9.9. Not sure why the fuses would be blown. I can see the tube having a short life, but the fuse blowing is a mystery.

I disagree. My old 1990 BMW 535i kept the same body style in 1995 for my 540. BMW changes the model name with change in model. More logical if you ask me. Just like my old Burmester MK3, after Burmester upgraded their MK2. Just my little opinion.

I am using a fairly large Philips 5R4GYS to great results. It sticks out nice and proud without cutting. I am also using Psvane CV181-T11 in my Oppo 105.

EML 5U4G works fine, see here: http://www.6moons.com/audioreviews/modwright11/3.html :thumb:

Thanks Srajan!
Really chomping at the bit now to get that power supply upgrade. After a premature failure of an EML, I have been a bit skittish. But the EML is like a girlfriend who screws you over but you love her still so much that you forget and go grovelling back. What are the other tubes used in the supply now? Looks like a substantial upgrade.
-
They are regulator tubes (13EM7,12EM7 and suitable subs.)
I don't know much about them.
-
Emission Labs has 1-yr warranty. My 300BXLS have been rock steady as have been two 5U4G. Had an issue with an earlier 45 but it got replaced under warranty and worked strong ever after. :thumb:

What makes the Emissions Labs 5U$G so special, as opposed to say, Radio Vacuum RCAs?
-
I've not done much rolling with rectifiers. I used to own Yamamoto SETs and in Japan Yamamoto is the importer for EML tubes. He recommended them so I bought a set of 45s, 300Bs and 5U4G from Jac in Germany to run my Yammies with. I loved the sound and didn't bother to stress over what other tubes might sound like. :oops:
-

I really don't think the EML 5U4G is that special. I think you can find old production 5U4Gs that sound just as good, if not better. Try an old Sylvania or Tung-sol.
-

I agree. It's very pretty to look at but, for the price, you can buy a few different flavors of English-made, coke-bottle rectifiers (Mullard or Brimar) that sound at least AS good as the EML. I think they're better.
I have an old-style Tung Sol and it's not bad at all. Not my favorite. I think I have an old RCA and must have found it pretty forgettable.
btw: My experience is with a Woo Audio WA22 and ModWright LS100. Similar findings with rectifiers on each device.

Hi Dan,
Any plan to still offer solid-state mods on the 105?
-
Hi Dan,
Any plan to still offer solid-state mods on the 105?
Honestly, I do not think the 105 would benifit all that much from a solid state mod. I had the 83SE solid state mod, and the stock 105 is better than that.
-
I had the SS mod on the 95 and it was really worthwhile. Of course the tube mod is better but even the SS was a significant upgrade. It made the 95 less edgy or sterile. Bass was more solid and refined too.
If you can't swing the tubes, the SS is a must have IMO
-
I have not planned to offer a SS mod for the 105, because it is so good stock! If I had felt that the LPS to replace the SMPS made a big difference and was feasible, that would have been a major part of the SS mod.
I have not ruled it out, but do not have a design at the moment.
Thanks,
Dan W.
-
My interest would be in the stereo tube mods,
plus SS mods to the remaining channels !
-
I am using a fairly large Philips 5R4GYS to great results. It sticks out nice and proud without cutting. I am also using Psvane CV181-T11 in my Oppo 105.
I am using the same tube combination in my Oppo 95 unit. I ordered the new PS 9.9 and PsVane WE274b replica 1:1 rectifier tube to play with when the new PS arrives.
-
I will be using a USAF-596 in my 9.9 once I get it.
-
David,
What rectifier is a USAF (I assume United States Air Force) 596?
-
OK, I found some 596 posts on the headphone forums. With your VT-99's and a USAF-596 in the PS you are gonna have one Sci-Fi (looking) Hi-Fi!
Those headphone guys DO dig up some unusual tubes!
-
I have posted a follow-up on Audiogon, after receiving my modified Oppo 105 back from Modwright. Thank you, Dan. Simply put, this player is amazing!!

Does anyone with the modded oppo have a picture of how the PS 9.9 looks like with a larger hole up top for a larger rectifier? I started giving it some though and am wondering how it looks. I was told i can send my PS back at anytime to get the hole added in, but i wanted to see how that looks. Thanks!

I have both the 95 and the 105 in house. The SS mod did help the 95, but honestly, the 105 is better overall stock out of the box, to the point it is simply not worth it.
Hats off to Dan for looking out for his customers on this issue. One of the reasons I will continue to support Modwright.
-

People should be getting this mod even if it is just for the cool factor. What's the point of having tubed equipment if you can't show off the tubes?
-
David,
With a pair of 6F8G's poking out of the player and a 596 rectifier in your PS, your setup is going to look VERY cool......and sound great as well!
-
I was curious about the 6F8G tube for the 95. Looks like an adapter is required to use it.
For now, the 5931 rectifier and 5692 CBS tubes are providing a life like sound playback. Currently listening to the Cream 2005 reunion on DTS Master Audio, and one feels like they are in the Royal Albert Hall. Hard to beat that! :lol:
-
Not a great photo but this gives you an idea of the 6F8G w/ adapter

Here is a link to a guy who has tried quite a few and HIS opinion:
(http://www.audiocircle.com/image.php?id=77626)
I have Tung Sol round plates and National Union round plates. They are both very nice tubes. The 'round plates' are though to be the best but who knows for sure?
-
Thanks for posting. Always entertaining to read opinions.
It never ceases to amaze me how different opinions can be about using the same tubes in the same unit, all based on the playback system as a whole.

I really like the Philips 5AR4GYS from Holland. :thumb:

What is the difference between a 5R4GY and a 5AR4?
-
I'm curious if anyone is connecting their cable box to the 105, and using the latter's DA conversion instead of the cable box's (or instead of the TV). Theoretically, it should sound better, but who knows with the compromised quality of the audio coming from the cable company.
Anyone?

dart6,
Go to page 10 and check out the link I posted there.
-
hi can anyone comment on the comparison between the modded 95 and the modded 105 thx
What I would like to know is how the modded 95 with the new 9.9 PS compares to the 105. I have the new PS on my 95. It is not a subtle improvement. Given that the 105 and 95 have the same DACs and the tube circuit board is identical (with some components swapped out), I suspect the sound is quite close.
-
I ordered and received a Sophia Electric 274b tube [Dan conferred with Sophia Electric personnel and they determined the rigid plate version (160mA) would be better than the mesh plate version (90mA) for use in the ModWright PS 9.9] and then the ModWright PS 9.9 arrived and both went into my system powering fully modded Oppo 95 player on April 30. I concur that the PS 9.9 (over the PS 9.0) with the ModWright Oppo 95 is not a subtle improvement, but a significant improvement that takes the music to another level yet.
:D
-
Those who have had both Oppo 95 and Oppo 105 can certainly chime in here.
The new PS 9.9 will improve the sound of the Oppo 95.
The Oppo 105 also has a significant number of improvements to the digital supplies to the DAC, overall build quality and I would expect changes to the DSP and designs, but I cannot comment there.
I DID compare the Oppo 95 and Oppo 105 with the new supply personally and felt that the improvement was far from subtle. The 105 is simply more natural and resolving. It is a beautiful sounding player!
Thanks, I hope this helps.

I have Tung Sol round plates and National Union round plates. They are both very nice tubes. The 'round plates' are though to be the best but who knows for sure?
Weird that all the tubes reviewed had a "forward/in your face" soundstage!
Not why i listen/invested in tubes!!
-
These 6F8G tube comparisons were from a Head-Fi member and perhaps the 'forward soundstage' is more so when using headphones, don't know. This is the opinion of one man who happened to have this extensive collection of 6F8G tubes and took the time to describe the similarities and differences as HE heard them.
IMO, the Tung Sol & National Union 6F8G's are great sounding tubes and I do not find the soundstage to be 'forward / in your face' while using either of these tubes in the Oppo 105, 95 or Sony 5400 for that matter.
Again, one man's opinion...............YMMV
-
I concur.
-
I can't wait to hear the PS 9.9 with my MW Sony 5400 and I know it's going to sound magnificient!
Wig :D

I am very curious about what has happened to all the activity on this forum. Has it gone somewhere else? Has the passion for all things Modwright Oppo 105 waned signficantly? As a very happy Modwright 105 owner, I am interested in connecting with others via these kinds of sites and forums. Anyone?
-
Well, the 105 still hasn't been out long. And this is a 15 page thread.
We'd love to hear your ongoing impressions with the unit!
Also, audio forums are slower in the summer it seems
-
We have remained quite busy filling orders for the 105 mod and have QUITE a number of happy customers. I believe the total exceeds 100 now, for the year!
We are also offering a 20% discount on the mod as part of a LIMITED TIME summer sale! July 8 - July 15!
Please also see the post and feedback from Infinity and Genesis Loudspeaker genius, Arnie Nudell!
Thanks,
Dan W.
-
Maybe it is because Modwright 105 owners are spending a lot of time listening to music. I know I am... That said, I do plan to write a detailed review after I've had sufficient time with it. Initial impressions are VERY positive!
More later...

Thank you for the responses. I am loving my modded 105! I’ve had it a few months, and I still marvel sometimes as I re-listen to my music collection. If I could change one thing, it would be to make it ever-so-slightly “sweeter,” or “liquid,” or “analog sounding.” Does anyone have suggestions for after-market tubes that might move it in that direction from the stock Harmonix tubes?
-
What tubes are you using jfz?

First of all you need to put at least 400 hours of playing on the cd player. The best tubes that are both clear and musical to me are as follows. I use Create Audio 5AR4, two Sylvania black plate coin base 13EM7. These 13EM7 are so much better than the Korean tubes supplied by Modright. You also want Tungsol black plate 6SN7 which will cost you 300 to 600 a pair. These will give you the natural liquidity that you are looking for. All these are new old stock tubes except for the Create Audio. Good Luck Jeff
-
Jeffy's suggestions are excellent ones. There are also a ton of very good vintage 6SN7s that are much cheaper than the TS BGRPs which will give you a big bump in sound quality over the stock EHs. Search for a 6SN7 thread either on here or head-fi.org. The Modwright Oppo BDP-95 thread has good suggestions too.
-
Thank you Jeffy and dminches!
-
Jfz - Dan himself recommends the Sophia Electric 6SN7 and the Mullard GZ34. The Sophias are supposed to be more "resolving, dynamic and detailed". The GZ34 from all accounts is supposed to add the touch of warmth you are seeking.
As everyone says all the time, everything depends on your system. If I had the money (and I don't because my ModWright Oppo 105 was just paid for and should ship this Friday :thumb: ), I would personally do the following: get a pair of well reviewed NOS 6SN7s, a pair of Sophia Electric 6SN7s, a Mullard GZ34 and a Create Audio 5AR4. As it stands, I'm going to run the stock tubes for a while and save up for the tubes mentioned above.
Jeffy - Would you be kind enough to share where you bought the Create Audio 5AR4 and the Sylvania coin base 13EM7? I have looked around a fair bit but I haven't found a source yet. You can PM me if you prefer.
Thanks!
-
Thanks Maritan. I don’t think it’s really a “touch of warmth” that I’m looking for. I think it’s something more elusive, subtle, and indefinable. “Liquid” does seem to fit fairly well, though.
I too would like to know where to buy the suggested Create Audio 5AR4 and Sylvania coin base 13EM7.

I'm using the tubes that came with Dan's mod. The output tubes are Electro-Harmonix. I don't know what the power supply tubes are.

I believe the 5AR4 is a Sovtek and the 13EM7s are Samsung.
-
To all MW Oppo 105 owners - Can you please some more feedback regarding its performance? I like to know how it performs as a DAC. Any comparisons to the other mainstream audiophile dac would be very helpful.
I'll throw in some names - how does the MW Oppo 105 as a dac compares to Berkeley Alpha Dac 2, Weiss DAC 202, AMR DP 777, Lampizator Level 3/4, Anedio D2, Nad M51, Perfect WAV Dac II etc etc.
-
Howdy,
Newbie question (prolly been asked over and over...sorry, if that's the case): Where are people sourcing 13em7 tubes from? Tubeworld only had 1 Sylvania coin base NOS 13em7 and I can't find any other place with them. Also, are there any recommended 6F8G/6SN7 adapters...eBay has a few but I'm not sure if some are better than others. One that I like are the Woo Audio ones but I'm not sure if it's still available.
(http://cdn.head-fi.org/8/82/82be606c_6SN7-6F8G.jpeg)
Same question regarding the Tung Sol NOS 6F8G tubes...eBay the typical place to get these?
Last question: For 6SN7 tubes, has anyone tried the Ming Da Meixing ones? They sure look interesting.
(http://www.hupse.eu/radio/tube_images/6SN7MingDa.jpg)
Thx in advance,

I am sure Woo's are fine. You can also PM 2359glenn. He made me my adapters.

The MW9.9 is Magical and excels in every area to include sound-staging, imaging and ambiance/low level detail. I too flipped my 13EM7s to 1950s Sylvania black plates...
