Title: Oppo UPD-203 Mods!
Post by: modwright on 11 Dec 2016, 12:19 am
Hi guys, I am thinking of a lower cost mod for the UPD-203, that may be SS.

Please let me know who is interested and how they intend to use this unit.

Thanks!

Dan

Dan, I definitely will be getting one for a spare HT where I have a 4K TV. I currently have a BDP-103D in there. While I use it more for HT, I do have a hard drive attached to it that includes hi-res files, including 2-channel and multi-channel DSD. I also on occasion access files from my NAS as the library is much larger.

Dan - don't really do disc playback these days (unless someone comes over).  I still have my Modwright (solid state modded) BDP-83 in the upstairs bonus room with a pair of GR Research N3s.

I would be curious..
Have been contemplating a Bryston BDA3 DAC fed by a universal that can output DSD via HMDI.
But a modded 203 might do the trick instead.
I'd be using for 2 channel primarily, with occasional duty in my theatre system for BD and multi channel.

The 203 will have the latest Sabre DAC and my intent is for it to be a great player AND DAC via digital inputs for DSD, etc.  A one box solution for all is the plan!

Thanks,

There are 3 different versions of the new Sabre DAC chip; which one will the 203 have?  The Sonica is supposed to have the top-of-the-line 9038 Pro, but on-line speculation has been that the 203 would have the lesser 9028?

Unless Oppo has changed their mind earlier press releases said the unit was going to feature the AKM 4458 DAC chip.

Post by: Ric Schultz on 12 Dec 2016, 05:38 am
Maybe Dan has this mixed up with the upcoming 205.  The 203 is really a replacement for the 103 and I am sure it will just have a switching power supply like the 103 and no normal direct DAC digital inputs.   The AKM 8 channel DAC should be more capable than the Cirrus they used in the 103 but the serious audio player will be the new 205 which is rumored to have the new ESS DACs in it......and why wouldn't they....they are already using them in the about to be released Sonica DAC and also have already started to use them in their latest portable headphone/DAC jobbie.

Information on the 203 is now on the Oppo site.  $549.  Taking preorders soon:

https://www.oppodigital.com/blu-ray-udp-203/blu-ray-udp-203-Images.aspx

The above internal pic shows the switching power supply and the AKM DAC in the middle of the multichannel output board and all the output op amps plus coupling caps on the input and output of all the channels (coupling caps not needed....the usual Oppo silliness).

The video on this thing could be killer.  There is a video on the site as well.  I imagine about 2-3 months before the 205 arrives but who knows.

Hi Ric, I had forgotten about the fact that the UDP-203 will not use the Sabre DAC, as the 103 does not either.

Yes of course the 205 will have the latest Sabre DACs in it.

Thanks for the link and pics Ric!

The SMPS is unfortunate and I agree about the coupling caps.

Post by: Phil A on 13 Dec 2016, 02:20 am
I'd think just like the 103 and the 105 that the 205 probably makes more sense to mod.  Not sure what the 205 will go for but the 203 was $549.  So by the time one gets thru with mods it may approach the cost of the 205.  Mine will be used more for video.  I have a main system and a back-up system for audio.  I'd also think that the upcoming Sonica DAC may even be a better candidate for mods for people buying it for audio only (unless they need a disc spinner).
Title: Re: Oppo UPD-203 Mods!
Post by: modwright on 13 Dec 2016, 04:30 pm
Hi Phil, that is typically why I have always only modified the higher end Oppos.

The Sonica DAC is of interest, but I don't know how many people JUST want a DAC.

The Marantz SA8005 is a CD/SACD player WITH spdif, toslink and USB DAC inputs for up to DSD2!  And it sounds FANTASTIC as DAC and player with our mods!

Thanks,

Dan
Title: Re: Oppo UPD-203 Mods!
Post by: Phil A on 13 Dec 2016, 04:42 pm
And more than likely Marantz will have an SA8006 around CES give or take.  They have recently announced the CD6006 (which also has a USB input) - http://us.marantz.com/us/products/pages/ProductDetails.aspx?CatId=hificomponents&ProductId=CD6006  and an SA10 - http://us.marantz.com/us/Products/Pages/ProductDetails.aspx?CatId=ReferenceSeries&SubCatId=&ProductId=SA10

I just received my 203 on Sunday and installed it yesterday.  Watched a few episodes of G.O.T. Season 6 on BluRay so far and it does produce really nice video.  In my case, it will be used 99% of the time for HT video, streaming services and related to a JVC movie projector.  If there is a modular, linear ps being considered as a drop in/plug and play ps that would improve overall performance, I would be interested in that.

Hi Ken and thanks!

The UDP-205 is the ONE that I am most interested in.  I believe, from what most have said, that the UDP-203 will be used largely as audio transport and video player via HDMI.  I agree that a drop-in LPS would be a good thing.

I was unsuccessful with this for the 103/105, but I have learned a few things since then.  We may be able to do this yet.  Heat is the biggest issue and I have a few ideas of how to address this.

Thanks,

Dan
Title: Re: Oppo UPD-203 Mods!
Post by: dminches on 21 Dec 2016, 12:24 am
Dan, can you explain what the LPS would power and what it would replace in the stock unit?
Title: Re: Oppo UPD-203 Mods!
Post by: modwright on 21 Dec 2016, 12:53 am
Hi, the UDP-203, presumably like the BDP-103, has a supply that provides 5V and +/-15V to the analog stage.  The 5V supply is HIGH current, because it supplies the video circuitry and all digital circuitry.  It is on the order of amperes, not mA.  As a result, if not done properly, in a linear power supply, will result in quite a bit of heat in wasted power.  These are raw voltages that are further regulated down to 3.3V for much of the digital and control circuits.  I believe the analog supplies may be regulated down to +/-12V.

Now this power feeds ALL video and digital circuitry, impacting DAC, HDMI processors, video processors, etc. As such, it SHOULD make a difference, to replace with a LPS.

The unit is fully enclosed, so the power supply (if linear), must have heat-sinks that conduct directly to the enclosure and reject heat right to the enclosure. SMPS - Switch-mode power supplies are very efficient and inexpensive, hence their use in most A/V players such as this.  Their downside is the amount of HF switching noise that they inject into the grounds and every other aspect of the player.  The SMPS's that Oppo uses are very well filtered, but it seems logical that if a LPS could achieve the same, it would be beneficial.

I will look at feasible options to address this, but no promises.  Others have done it and they are available, at least for the BDP-93 and BDP-103.

Thanks,

Dan

Dan are you sure. The OPPO webpage shows "" The UDP-203 features a premium 32-bit DAC from AKM, the AK4458VN, which is an 8-channel DAC with support for formats such as 192 kHz / 32-bit PCM and multi-channel DSD.""  https://www.oppodigital.com/blu-ray-udp-203/

Hi guys, coffee on board and here is to clarify a few things:

1) The UDP-203 is an interesting unit and I do see the potential for mods to it, specifically the power supply.
2) If there is interest in analog stage mods for this model, I am also willing to pursue it. Most people seem to use the 95/105/205 for audio use, which is why I have always offered mods for that. If you are interested in mods only for the 203, please let me know!
3) The UDP-203 does NOT use a SABRE DAC, it uses an AKM DAC - I misspoke. The AKM DACs have always been very good!
4) I am excited about the UDP-205 because the 95 and 105 have been huge successes for us and the 205 is the next in a long line of exceptional players from Oppo.
5) Yes, a new thread will be started now, for JUST the UDP 205.

Thanks guys!  :D

I was up into the middle of the night just playing with it.  I will say that the audio from just a few cuts was a tad smoother and more refined in my opinion vs. the 103 which was a bit shouty
Title: Re: Oppo UPD-203 Mods!
Post by: undertow on 22 Dec 2016, 03:56 pm
From the early adopters I have read that the 203 is not quiet as good with 2 channel audio.. But who needs that these days :roll:

In any case it was built to a purpose. Be a 4k machine 1st and foremost with universal appeal, and be at a price point that makes most Videophiles happy.

Supposedly from the professional engineering standpoint the 103 had a higher current, low 5 volt power supply which was very solid for audio. I guess the 203 has a more run of the mill 12 volt supply used in most DVD players these days. However, the 103 and 105 also had the outboard wireless dongle. The new 203 actually can create some noise with the internal wifi... Again words from designers I was reading not mine.

The loss of video apps is slightly strange to me on the 203 honestly. You would figure they want to appeal to the universal crowd and keep the "Smart Chip" in there to compete with 80 dollar blue ray players as well, but I guess they figure a lot of people will just feed the HDMI back from the TV or use other units that have the smart apps on them I don't know?

Problem with this is not every HD TV even has an HDMI out to feed back to the OPPO in's HDMI to take advantage of the video and or audio processing power, most of the Smart TV's just have inputs so for others they will have to have a Roku or playstation etc... in order to run them I guess.

Just a warning for those looking at the new machine as it did add 4k but cut corners on a few other things in the universal audio/video realm if they are of any importance to you. Also, no mention if this unit even links up to the OPPO media app... It may have been dropped as well with the smart chip for netflix etc...
Title: Re: Oppo UPD-203 Mods!
Post by: modwright on 22 Dec 2016, 06:07 pm
Thank you both for the photos and insight into this new player.

Indeed, it is built to a price-point and Oppo has always excelled in this.  The 205 will indeed cater to the audiophile, whereas the 203 is foremost appealing to the videophile.

Interesting about the higher voltage, lower current supply.  This MAY lend itself more easily to a LPS for improved video and audio performance.

The 2CH Audio is simply sourced from the FL/FR outs, like the 103.  This allows them to use a single DAC chip (multi-channel) for both Stereo and MCH output.

I only listened to a couple of things vs. the 103D, but preferred the 2-channel from the 203.  More refined on what I listened to.  I remember reading somewhere the Media Control App is coming in January.

The streaming Apps I've read are to come as well
Title: Re: Oppo UPD-203 Mods!
Post by: undertow on 22 Dec 2016, 06:25 pm
Yeah I still have a little issue with them dropping the "Smart Player" because even for most movie, video people these days do almost everything via streaming. I guess you can pull from other sources over the network if you want to get into all of that, but especially being its a 4k player you would assume that today it's rare to sell 35 dollar 4k discs to everybody and have to use the transport?

Seems a mistake removing the smart apps in my opinion directly on the machine. Not to mention if you want to process thru the oppo without an optical disc you are forced to essentially run another HDMI to the input if you have a unit to pull up the APP.

Ha, but I guess even video guys might have an old playstation hanging around they can run their Amazon or Netflix on! But it would be nice if the 203 internally processed it. Oh well.

As for stereo outs I believe all Oppo really ever did was simply jump another parallel set of RCA jacks out of the back and name them "Stereo" to make you feel better. It was always tapped off the 8 channel DAC for the last decade I assume. I don't believe they ran entirely separate 2 channel DAC boards so it always derived from the FL and FR on the chip.

Beyond that from my personal experience I was never that impressed with any of Oppos sound in stock form. Especially the overpriced Balanced BDP 105. I think the BDP 103 for the money was at least as good with most High res systems in single ended 2 channel anyway.

But both excel with a good custom Linear Power supply of course.

I've just seen this - https://www.engadget.com/2016/12/13/oppos-first-ultra-hd-blu-ray-player-is-a-tribute-to-physical-me/

Earlier reports indicated that streaming Apps would be coming but the above indicates no (and it is more recent).

Not a big deal (to me) as my 4k TV has Apps and I have Roku boxes and Firesticks.  I've actually never used any of the streaming Apps from any of my Oppo players.

Post by: Phil A on 22 Dec 2016, 06:31 pm
I also have two 103Ds.  One is in the main system and it has only been used for video (have a music server and DAC).  The other is in the room where I just put the 203.  I'm taking that 103D into the bedroom system and rotating a 93 somewhere else.  I can access my NAS from the 103D and the bedroom system feeds the outdoor speakers.  I am into file playback so disc spinners other than for movies don't hold great interest for me personally.
Title: Re: Oppo UPD-203 Mods!
Post by: undertow on 22 Dec 2016, 06:48 pm
Well and there in lies the real point... Oppo for some reason really stressed on building a better transport into this one which at this point with Blu Ray, or CD, High res audio servers, or 4K is about 5 years behind! Should have kept streaming services on board... I am not a buyer, because I already have about a 1000 mod investment into a 103 with the top Sabre DAC board, and 2 amp linear power supply, but also can care less about 4k much like 3D honestly. Unless you like hanging out at best buy watching flowers grow, or sea creatures float around all day on demo :-)
