Title: Oppo UDP-205! The New Truth Mod! The Next Level!
Post by: modwright on 21 Dec 2016, 07:18 pm
OK guys, so Oppo has FINALLY published info about the UHD-205 4K player!  I know that many have been waiting for this and asking about it.

I am very excited about it and I plan a totally new and re-designed mod for this, beyond what we have done for the Oppo 95 and 105/105D. I have some great ideas up my sleeve, but I won't know what is best until I actually get the first unit in here.  I too am waiting for early release info from Oppo.

Like we did with our Marantz SA8005 mod - To date the BEST music only player mod we have ever produced! - we will offer a tiered discount structure for the first ten customers to sign up and pre-pay a deposit.

If you are interested in getting on this list, please simply email us at: modwright@yahoo.com.

I won't start taking deposits until I have a unit in house and have a firm handle on the mod.  You can however, get on our 'pre-order' list by simply notifying us of interest.

Thanks!

Dan

I plan to pursue a circuit similar to that used in the Marantz SA8005 mods, because I have been so pleased with how that turned out!

It all depends on the unit that Oppo produces however of course.

Thanks,

Dan

Any solid state mod? to keep the player 1 chassis instead of 2 chassis?

Post by: modwright on 22 Dec 2016, 06:25 pm
That is certainly a possibility!  We did for the 95, but not for the 105.  I think it is time to look at a lesser cost and one-box SS mod option for the 205.  We are working on some discrete analog circuitry that would fit in well here!

Thanks,

Dan

Strictly rumor and from a questionable source - 205 will feature a SABRE DAC that is the same one that will be in their new stand alone DAC. (Posts 106 & 107)
http://www.avsforum.com/forum/149-blu-ray-players/2678801-official-oppo-udp-205-uhd-blu-ray-player-anticipation-thread-4.html

http://oppodigital.com/sonica-dac/

Still early and hard to find solid info. This would make it fundamentally different from the 203 which features an AKM DAC

Based on test results of discrete opamp R&D that I have been doing with Alan Kimmel, I expect that we will likely offer a lesser cost SS mod for the UDP-205 in addition to our tube mods.

Very pleased with the sound of the new discrete design!

"A lesser cost SS option"
This has me interested :)
Title: Re: Oppo UDP-205! The New Truth Mod! The Next Level!
Post by: modwright on 5 Jan 2017, 04:58 pm
The discrete op-amp design is really eye opening!  I have always rejected opamps for their inherent feedback based design, but what I am hearing here has me thinking otherwise!

We still need to shrink the PCB size per op-amp and of course make custom boards.  I am thinking our own Super Voltage Regulators too and this could be exceptional!

This has the potential for MCH and well as 2CH applications and would not require an external supply or any chassis machining.

Thanks and stay tuned!

Dan,

Is there any chance you'd do a mod for the Opposite Sonica streamer/DAC?  Would love to have modwright magic on something purely as a streamer.  A new replacement for the Transporter :)?

Jim
Title: Re: Oppo UDP-205! The New Truth Mod! The Next Level!
Post by: modwright on 15 Jan 2017, 11:23 pm
I certainly would be! Is it a streamer and DAC? I know it uses the latest Sabre DAC chip and promises to be exceptional.

There would be no switched mode power supplies and no video circuitry. As such, it would be a great audio only solution!

I would consider both SS discrete one box mod options as well as tube mods with external tube supply.

All interested, please let me know! I have both new tube and SS circuits that would work very well here!

Post by: modwright on 16 Jan 2017, 04:58 pm
I noticed that it is $800 too, which means you are not paying for the video.  I wonder if the analog and DAC circuitry is better implemented or the same, comparing the Sonica and UDP-205.  I would expect that they did not reinvent the wheel, and thus they are very similar or the same.  The good thing however, is that ALL circuitry is implemented via a linear PS and no switcher is used at all.

I am excited to explore both the Sonica DAC and UDP-205.  It looks like the DAC will be out first!

SamS at SH Forums (an Oppo beta tester) has suggested that the BDP 205 may be just a little more upscale than the Sonica, in terms of sound quality.  That may not matter if the post-DAC circuit is changing anyway.

Did he actually say that?  He said they may have a few tricks up their sleeve.  Has he actually listened to both side by side?  Maybe I missed that thread.

Post by: modwright on 16 Jan 2017, 08:52 pm
I agree that I am a bit surprised to hear this.  The DAC is their dedicated music device.  I would expect it to be at least the equal of the 205.  To be honest, I would be surprised if the DAC and analog circuit are actually any different at all.  The main difference as I see it would be the power supplies.

I posted "suggested" and "may".  That could hardly be less definite or clear.  He may know something, some features of the design may not be finalized, or maybe Oppo just wants to increase anticipation, who knows. I think his point was that the Sonica and the 205, despite using the same DAC chip, may (emphasize may) have some differences in implementation.

You can see the inerds of the Sonica on their site;

https://www.oppodigital.com/sonica-dac/sonica-dac-Images.aspx

It uses both a switched mode power supply for everything but the analog board.  The toroid is for the analog board.....just like in the 105.  This is not going to sound very good stock.....needs a lot of work.  I am pretty sure the 205 will be the same.  These new Oppos will keep us modders busy for awhile.  When the Sonica was first announced I emailed Oppo to see if DSD512 would be supported as all the first reports were that it could only do DSD256.  I told them all of my customers (slight exaggeration) would not buy anything unless it has DSD512 as we are all (he he) moving over to HQPlayer with upsampling.....well, guess what, the new Sonica can do DSD512.  Helps to push people sometimes.
Title: Re: Oppo UDP-205! The New Truth Mod! The Next Level!
Post by: modwright on 17 Jan 2017, 07:04 pm
Thanks for sharing Ric!

It is as I expected, but I am surprised to see the SMPS there.  The analog and digital stage look virtually identical to that in the players.  The DAC is pin-compatible, so they would not re-invent the wheel.

There is a WiFi card inside of course as part of the streaming connectivity.

I am still surprised by the SMPS.  In the video players, the video takes a HUGE amount of current, hence the decision to use a SMPS.  I expected that they would just take the digital supplies from the LPS.  Again, my guess is that they moved the analog stage, PS and all, from the player to the DAC and kept the DAC supplies the same also, from the SMPS.

Definitely room for improvement!

It seems that Sonica DAC does not include the ES9038pro, but the simpler version of this new chip, ES9028pro... Or it may be something wrong with the marking of the ESS DAC chips, Oppo is using....

I found another more detailed picture of the DAC chip inside Sonica. There is about ES9038Pro...
Now is the question: why we have different marking for the new ESS DAC chips...?

Post by: Ric Schultz on 23 Jan 2017, 04:50 am
The markings on the 9026/9028/9038 that were first shown on the ESS website (and still there), etc. were from pre production samples.  Hence, no normal labeling.  All the ESS DAC chips look like the ones in the Sonica Picture, which include, what I presume to be batch/date codes.  You cannot tell the difference between a 9028 and 9038 unless you can see the writing....which is smaller than the pre production batches. 
Title: Re: Oppo UDP-205! The New Truth Mod! The Next Level!
Post by: Coris on 23 Jan 2017, 08:11 am
Thanks Ric for explanation. It make sense also...
As the pre production batch is known it came out with some issues, it may be advisable avoiding the use of that specific marked chips (which it could be on the market out there)...

It does have a LPS for the analog audio section.  It also uses a SMPS for all digital and control circuitry. I would like to look at replacing that with a LPS also.

Excellent, reading that confirms to me that they put the same digital and analog audio 'engine' in the Sonica DAC.  I have the mod for that complete, so as soon as the UDP-205 is available, it is just a matter of adapting the mechanical layout to accommodate the 205.

Good to know that they are FINALLY about the release the 205!

I can tell you based on my results with the Sonica DAC, that the UDP-205 is going to be GREAT with our mods!

No clue on how long it will take. I assume many weeks. Been waiting for Oppo to release this for many, many months, so I am not in a huge hurry. I am practicing my patience.....

Have to figure out another GTG at some point. My HT/2 channel system is kind of "Shoe-horned" into a room and acoustics are a nightmare. I have it so the sound is pretty good at my seat, but everywhere else sounds pretty bad.

Maybe you should have had it shipped to you so you could have checked it out for awhile?  Dan won't even start the design until next week after he gets back from Axpona, then he has to mod his own unit, test it, etc before he starts on anybody else's.  Did you get the email from Kristen?

I have learned patience at this point. I'm always afraid that extra rounds of shipping and packing/unpacking is more likely to lead to issues.

I know Dan has a busy schedule between regular work, Shows, and design. I am more than happy to wait. If I am correct, this will be a player that may well be my last (barring unforeseen future technologies).

Not yet. Expected delivery is tomorrow "by end of day". I hope to have it hooked up Thursday evening and start listening Friday.

I keep telling myself "Patience young Weed Whacker" using the Voice of Master Po.

My fear in attempting to describe the sound improvement is that I only have an unmodified Oppo 95 for comparison. I'm fairly confident the sound will be easily better, but that may not be saying too much. I know what I always think of as the shortcomings of my "Frankenstein" Speaker setup as well as room limitations. I'm hoping that those issues will no longer be as problematic and everything more enjoyable, especially the more poorly recorded discs. Well recorded discs sound pretty good already and I will focus on those to see what the changes are. I'll run through my usual pieces first, then go from the there. I'll come back to those "Reference" pieces after the player has had some break-in time. Not sure how soon I want to put the 5R4GYS into the PS. The impatient part of me says to put it in right away and then I can switch back to the supplied tube later for comparison.  :green:

Congrats John.  What are your impressions.  Audio and video quality.
Only listened to redbook CD's last night.

Detail. Far and away more detail. The differences in the little things is amazing. I'm so used to hearing things the way I've heard them for years at home, it's so different. Examples that are most obvious are in the background stuff like chimes. Before they were "just there". Very nice. Now, each of them seems to occupy it's own space (I guess this could also be described as even greater focus) as the hand is drawn across. Cymbals are  a whole new thing - you can tell the differences in how the drummer strikes them to get slightly effects.

Dynamics. They are greater. I am not turning up the volume as far to get to the levels I am used to. I do not understand how, but it is obvious.

Bass. Wow. Much better, and I am admittedly a bit of a bass nut. More authority.

Instruments pick up clearer tones and subtleties - strings are the most obvious that come to mind. As the bow is changed in orientation to get different sounds, it is obvious.

I'll check back in later in the day with more after I listen to some SACD's and DVD-A's, as well as blue rays. Gotta do some chores for the next few hours and hope to get back to it in about 3 hours.

Thanks for the early feedback!  We are very excited about this mod for the UDP-205 and Sonica DAC from Oppo.

This mod actually costs us much more in parts than our other mods, with the four Lundahl signal transformers, but the performance is worth it!  We did not raise our mod price from the 105/105D to the UDP-205!

Wow!  This is a nice sounding unit!  I admit I haven't tried it with the "stock" tubes; right now I'm using a Phillips 5R4GYS rectifier and some Phillips/Amperex E188CC's.  Bass is cleaner and stronger than with the 105 mod, and the midrange seems "smoother".  I hadn't thought those areas were a problem with the 105.  I also have a pair of Telefunken CCa's to roll in, and a couple of different vintage Mullard G34's for the rectifier if I feel like it.

Enjoy!  It is a step up in every way from the 105/105D mods.  We re-designed our mod circuit from the ground up and Oppo certainly upped their game with the UDP-205 also!

Having said all of that, the 105/105D with our tube mods is exceptional and we have sold hundreds of them! This is simply the next level, as we continuously strive to better our designs and bring you closer to the music.

Thanks,

Dan

I wasn't sure about this yesterday, I thought t might have been the (relatively unfamiliar) program material, but today listening to some music I recently had up in the 105 I notice that the stereo image is larger; wider, deeper, higher.  It's as if I changed the positioning of my speakers.  Again, not the type of change I expected, but it's an improvement and it's nice.

Wow!  This is a nice sounding unit!  I admit I haven't tried it with the "stock" tubes; right now I'm using a Phillips 5R4GYS rectifier and some Phillips/Amperex E188CC's.  Bass is cleaner and stronger than with the 105 mod, and the midrange seems "smoother".  I hadn't thought those areas were a problem with the 105.  I also have a pair of Telefunken CCa's to roll in, and a couple of different vintage Mullard G34's for the rectifier if I feel like it.
Looking forward to hearing any impressions you have about rolling the tubes in this beautiful unit.

I'm still getting this "broken in". I've gone back and forth a couple of times on the tube for the PS and am wondering if I can gain anything by swapping the tubes out in the Oppo.  :dunno:. It would be fun playing around, but afraid of spending $$ on tubes with no real gain in SQ.

I think I'm pretty sensitive to any sense of "glare" or "edge" in the 2-4 Khz range, so definitely don't want anything that could make that an issue.

If you couldn't improve the sound by changing the tubes in the Oppo, it might the only tube audio circuit ever where that would be the case.  Yes, you might be talking about a bit of money, but how much did you pay for this unit in the first place??  From my research into the 6922 tube family in general, $150-200 will get you a nice upgrade, and spending more will get you more.  At the moment I'm lucky enough to have been lent some slightly used high quality NOS tubes; this is a common tube family, check around.

You should try a pair of Mullard CV2492s.  They are slightly warm which may align well with your comment about avoiding edge.  I have used them in a number of components and always enjoyed the sound.

Thanks for the input. Trying to do some research. Saw one review on different tubes in this category which included the Mullard and it turns out the reviewer didn't rate them well. Then later found out he got a hold of some "counterfeit" ones for his testing. Makes me a bit paranoid. Gotta find a good source. The Siemens seem to get a lot of positive reviews and comments.

Research continues. Still enjoying the heck out of what I'm running now. Incredible machine IMO.  :thumb:

Genuine 1960's Mullards are generally highly regarded for their very smooth sound, as Dave says.  He has the Modwright Marantz which uses the same tubes in a very similar circuit to the 205 mod, so maybe he will post some of his experience with more tubes.

Rob, the marantz tube section uses a 5687 instead of the 6922 family.  Both are nice tubes but there are many more options with the 6922 so you are lucky to have that option.

After a couple of days of burning in the UDP-205 with Truth Mods is sounding really good. I haven't even pulled out the NOS tubes yet. The sound is so smooth I don't need a preamp, just going direct to the Benchmark AHB2.

I'm in my second day of listening to a pair of Mullard 6922 10M tubes (1966 vintage) from Brent Jessie.  They compare very favorably to the (borrowed) Telfunken CCa's, at a much lower (though not cheap) price.  True to their reputation, they are very smooth through the midrange, with powerful clean base.  The highs are not harsh, but perhaps not quite as "airy" and detailed as the CCa's.  I'm pretty sure I prefer them overall to the Miniwatt E188C's, but need to listen for a few more days at least for a final opinion there (the E188C is much closer in price to the premium Mullards than the CCa's are).

There are so many good sounding tubes of the 6922 variety.   I probably have 10-15 different pairs.  Unfortunately I don't have any equipment which uses them.

I wish my Marantz SA8005 used this tube.

The Marantz uses the 5687 because of the different sound of the player and voicing.  The UDP-205 mod was designed after the Marantz and I used the 6922/7308 because it just WORKS with the SABRE DAC chip.

For those who haven't yet heard, the 205 is getting free MQA compatability.  Be aware, though, that unlike other beta firmware updates, this one is not reversible to previous firmware.

I have definitely been lukewarm about MQA, but I have to admit getting MQA compatibility with my existing hardware, for no added cost, is kinda cool.  I may even resubscribe to TIDAL just to see if "full unfolding" is noticeably better than the "partial unfold" I had previously (which was not impressive enough for me continue my TIDAL subscription)

Did you see any technical reason in the parts choices in the Sonica as opposed to the 205 why the MQA firmware could not be applied to the Sonica?  They implied in response to someone on another forum with the question that the "decoder" could be an issue.  I was under the impression the DAC sections were basically identical.

Apparently it’s the MediaTek chip set doing the decoding; I don’t know if the Sonica has that chip set (which is multi-channel, although not used that way for MQA)

that was me.   Here is what they sent

" The Sonica DAC uses a much lower powered decoder so we are not sure that we will be able to add MQA to the Sonica DAC either as files on attached USB storage or as files that you playback on a computer through Asynchronous USB to the DAC.

Forgive me if this is a "Silly question"....... I still don't completely understand bits.

I've recently been reading through other threads which tout the benefits of "re-clocking" in the Digital chain, I was wondering if this type of product could be used with the 205, and if so how?

I have slowly burned most of my CD's to FLAC using dbpoweramp. I love the convenience of having everything (except Hi Rez) on a single HD. Could a re-clocker be put in between the HD and the 205? Would it actually help? (I love the sound of my 205 compared to what I had before, but always in search of further improvement.) A member of an Audio group I recently joined loves his and suggested I try one in my system.

I also need to figure out a better user interface than the Oppo phone app, but that's another topic  :green:
Title: Re: Oppo UDP-205! The New Truth Mod! The Next Level!
Post by: modwright on 19 Dec 2017, 09:55 pm
There are some devices that are USB in-out that do some sort of re-clocking.  I have not tried them, but it stands to reason that they could be beneficial.

We are not doing anything inside of the Oppos regarding re-clocking.  All clocks are small, surface mount and well done inside the unit.

Having said that, I am hearing of improvements from people using external USB-USB re-clocking devices.

Thanks,

Dan

Post by: rbbert on 20 Dec 2017, 04:51 am
My guess would be that reclocking benefits the situation where a server is using the asynchronous USB input rather than an external HD using one of the USB A inputs.  Technically difficult at best to “reclock” those, since they don’t use a separate clock (only the ones internal to the Oppo)
Title: Re: Oppo UDP-205! The New Truth Mod! The Next Level!
Post by: modwright on 20 Dec 2017, 06:14 pm
Good point! I was not thinking of the different way that the USB data is handled via non-computer USB inputs.  It is raw data into the Oppo processor via this type of USB input.  The USB computer input IS truly asynch USB with clock in the data. I cannot say which sounds better, to be honest.  I have pretty much always used computer USB input.  I have used a USB thumb drive or external USB drive directly connected also.  It works fine, but I have not compared the two for sonics.

Thanks for clarifying this!

Would there be any benefit if I were listening to spinning silver discs and then using a cable out (SPDIF, USB, whatever) from the Oppo 205 out and then routing it to a reclocker, then back to the same digital input type, using the 205 (ModWright) as DAC?

I have had my fully modified Oppo UDP-205 for some time.  I have gone through the ModWright modified Oppo ladder.
I must say that this player is phenomenal...both as a player and a DAC (Nakamichi 1000 mb transport).
I have enjoyed both CD's and CDR's.  Great balance, excellent 3d soundstage, and musically satisfying.  Dan and his team continue to amaze me.  The modifications are of excellent quality.  His support staff is exemplary (thanks Kristin).  I have not compared it to the mega bucks players, but I feel I don't need to.
If NFS Audio ever does a show again, we will certainly use this player.  For now, I'll be enjoying it at home.

We have plenty of parts for the mods, that is not an issue.  It is just a matter of how many Oppo's are in circulation.

Most of the time, people simply send us the UDP-205.  We buy them and modify them for use at shows and sell them as demo's.  However, the typical case is for people to send us their UDP-205 for us to provide mods.

The PCBs and all parts that we use for the mod are all readily available and not a limiting factor.

The DAC on the UDP 205 with Dan's Mod makes it a true workd class DAC comparing to the Chord DAVE which is over 12K the  modded Oppo never embarrasses itself.  People will miss Oppo legendary status of designing the best players in their price range for 14 years. I am glad I hav one of Dan's player and regularly use it as my reference DAC and player for reviews of headphones and other resources. If you own an Oppo UDP 205 get it modded as it will take you to the top of heap in sound quality. I love the tube compliment as well. I am using the Genelex 6922 and after rolling the rectifier tubes I love the stock Sovtex bass  better than other sos it remains my tube of choice

https://www.stereophile.com/content/oppo-udp-203-vs-cambridge-cxuhd (https://www.stereophile.com/content/oppo-udp-203-vs-cambridge-cxuhd)

"…….., Recently, my cousin brought his fully modified Modwright Oppo 205 over to my place and I had a chance to take it up for a spin in my dedicated stereo setup. So I disconnected my DCS Vivaldi full stacks (DCS Vivaldi DAC) and inserted his fully modded Modwright Oppo 205 in the chain and started listening to some CD and SACD as well as some hi-rez digital download files streamed through the Oppo 205' USB asynchronous DAC port on the back. And his Modwright Oppo 205 was connected to my Audio Research Reference 10 linestage preamp and my D'Agostino Momentum 400 monoblock amps (2 pairs in bi-amp mode) driving my new Magico M6 speakers. It took me as a surprise. His Modwright Oppo 205 performed and sounded superbly and did not embarrass when used in my reference stereo setup. It wasn't on the same level as my DCS Vivaldi full four stacks (Vivaldi master clock, Vivldi upsampler, Vivaldi CD/SACD transport, Vivaldi DAC) but hey my full DCS Vivaldi stacks cost around $125k and his fully modded Modwright Oppo 205 total costs of only $5k ($1300 stock 205 + $3700 total costs of fully modded Modwright labor included). But as a single one-box digital front end universal player/DAC the Modwright Oppo 205 sounded and performed spectacular, very resolved, highly musical with fleshed out mids (vocals) and other instruments elements. Sounded very analog like and natural or organic so to speak and with very good sense of image and soundstage depths. Transparency and inner details and nuances are excellent. There were good amounts of air and space between instruments and vocals. PRAT is very good too. The noise floor was surprisingly very low, approaching and was pretty close to that of my own DCS Vivldi full stacks. Overall the Modwright Oppo 205 IMO performed on the similar or same level as those single-box digital front end players/DAC in $10k to $15k region and up. Sonically, it rivals an entry level Esoteric player/DAC."

We are still very much modifying UDP-205 and Sonica DACs!

As a recent owner of a Modwright Oppo UDP-205, I just want to say how VERY happy I am with this unit! I went from a stock unit to the modded one and there really is no comparison. It truly sounds like you are listening to analogue. On more than one occasion, I found myself thinking while listening; this record is very quiet and sounds great, only to realize that I am listening to a CD. I love the fact that this player can do it all for me and makes digital sound so much closer to analog. The other great feature of this mod is that one can view blu-ray discs without having to utilize the tubes. Very nice!

I should point out that my observations have been from using a 4 notch Blackburn Mullard GZ34 rectifier and 2 RTC E188cc tubes in the Oppo. I have not tried the stock tubes that come with the mod and I most likely will never use them, since I am so happy with the NOS tubes.  I have not tried streaming, although no surprise, it's also supposed to sound excellent.

I am very sensitive to "digital glare" and there were a number of rooms at the Dagogo Show in Oakland that I attended this past summer whose playback systems consisted of well respected high end DACs and their sounds literally drove me out of the room after a few minutes. Thankfully, I do not have to endure that at home.  :D

This is an interesting option , I would have gone for modwirght Mods but have a PS audioDirectstream DAC and use the OPPO only as transport most of the time  I also use it via it's analog output as a 5.1  channel HT system with seperate speakers Subwoofer and separate Wyred4sound MC 7150 ( very sweet sounding unit ) , I am wondering if this $ 318 Nobosound  LPS would make any significant difference ? has anybody used this Mod ?

Interesting info.

Has Dan ever made any comments about these various options?

I'm curious as to how much benefit you get from any of these. I can understand the benefit for the Video and if you used the digital output Audio, but if you use the Analog output, how much would be gained?

Still thinking about it if it really helps the Video. Love the image I get with the 205. If it can get better  :drool:

I have not heard all of the different LPS's. A LPS produces less HF noise and is preferable.

Thanks,

Dan

Where should the Audio Magic Pulse Gen be placed when a LPS replaces the stock power supply board?

I have a stock 205 I use for video, with a LPS, and can assure you the video is improved, noticeably but not by a huge amount.

I would still install it at the AC mains. It will kill all RFI/EMI noise generated inside the player. The SMPS is one source of course, but there are plenty of noisy video/processor chips adding their own contribution of noise too!

Due to having to solder the Audio Magic leads this installation was a tad more complicated than in my stock 205 but all went well.  There is a bit less "glare" to the sound, something I didn't notice until it was (is) gone.  My early impressions are that the LPS makes a more obvious difference for video than for audio, but still worthwhile even for audio only.

I got my Oppo UDP-205 mod from Dan in September 2019.  I had my 205 since it was first released, so I was very familiar with the stock sound.  I was very happy with the improvement in the sound quality after the mod and am glad that I had it done.  I received great service from Modwright Instruments.

I used the mod with the tubes supplied by Modwright for two months before I ordered better tubes from Andy at Vintage Tube Service.  It now sounds even better.  I like that I can experiment with different types of tubes if I want to change things up.

The thing I love about the Oppo UDP-205 is that it plays native DSD512 and DXD files, which sound super smooth with the mod.

Hello, I am geoffny, introducing myself as I am interested in the ModWright  upgrade for the Oppo 105d.  I see a lot of good information here and look forward to learning.  Thankn you.

I understand that this mod is no longer being performed by ModWright, but they say I may get lucky and find one among the membership.  If anyone knows of one, please pass along the info.  Thanks!!

Also, if anyone has experience / good info on tube rolling that would be appreciated.  I understand that the Gold Lion and some Russian made tubes are supposed to really make a difference.  I am anxious to check it out.

I currently have a NUC running Roon ROCK connected directly to my Oppo UDP-205 Mod via a nice quality USB cable.  The USB cable is plugged into the NUC's USB 3.0 port.  All of my audio gear is powered from a PS Audio P12 PowerPlant.

I want to move my NUC into an equipment rack that contains my NAS and a UPS.  The ethernet connection from my equipment rack to my audio gear is optically isolated.

What is the best way to galvanically isolate the USB connection from my NUC to my Oppo?  The solution must support the capability to play DSD512 and DXD files.

Currently, I connect my Oppo UDP-205 Mod directly to mono block amps and subwoofer amps using the RCA connections.  For each channel, I split the RCA connection from the Oppo to feed both the mono block amps and the subwoofer amps.

The Oppo has both XLR and RCA analog outputs.  My mono block amps have both XLR and RCA inputs.  My subwoofer amp has only RCA inputs.  I would like to connect the Oppo XLR to the mono block amp and the Oppo RCA to the subwoofer amp.

Will using both XLR and RCA outputs on the Oppo at the same time damage anything?

Because they are essentially wired in parallel, this will work.

Note however, that when you connect the RCA outs, you are grounding pin 3 of the XLR out, making it also, single ended. As long as the amps don't have an issue, then no problem.

Thanks,

Dan
