Last night I built linear power module for upgrading OPPO 93 visual and audio performance.

This module is 100 % same size and dimension of original OPPO SPMS power board.



It is very easy to install .



Just plug 3 cables and tighten up 5 bolts as shown in picture.



Contrast is much improved, color became richer, video noise and edge became much cleaned.

audio performance is also improved.



I would say PQ of this unit is 75 from 40 ( original ) , audio is 80 from 60 ( original).



I used coaxial cable for audio connection to my AV peocessor.
JVC X-3 3D projector with 110 " for video evaluation.

linear power module



Linear power module is replaced with stock SMPS power board.



Replacemet work is done with inserting 3 cables and 5 bolts. No soldering is neeeded. It can be done within 10 minites



I also chaned to 3 prolong AC plug which supports ground.

Lee my browser has consistently NOT been showing your images. I've not had this problem with other posts/images both here and other forums on AVS. Not sure what the problem could be.

Is anyone else not seeing the images Lee includes with his posts or is it just me? I'm using Firefox 11.0.

Thanks Lee, very much appreciated. I can only imagine the time and effort you put into upgrading the 93. You and Ayre are the ones who have bumped the PQ level of a very popular company. Some people don't appreciate what custom mods can do.

Thanks Talk2me !!

I always want to extract full potential of well made OPPO 93/95.

I know Ayre DX-5 is the only machine I can agree with my principle.

But I can't spend 10K$. And I need 3D support .

I heard that Ayre dosen't have inrention to make OPPO 93 version of Ayre Dx-5.

So I made up mind to make my own dream source machine.

Fortunaetly, Living in Korea provides the access necessaey parts and Troidal transformer / PCB custom made shop rather easily.

But Lee, ain't you simply making a BDP-95 of sorts? Its also has a linear PS and separate supplies for audio and video circuits...

I only see placeholders with Safari 5.1.5, but if I click the placeholder and open it in a new tab, I can see the picture.

. . . .

. . . .

Lee, you are using HDMI for video right? So how do you account for, say, improved Contrast?

I mean the stock 93 already outputs "black" pixels in the content as HDMI Black and "reference white" pixels in the content as HDMI Reference White. This is easily verified with an HDMI digital data capture.

What the display does with a Black pixel or a Reference White pixel input signal can not be altered by changing the power supply in the player.

So were does the improved Contrast come from?

Checked out your blog. Fishing and electronics.
Can't think of anything better!

Hi Bob

I am using HDMI 1.

I would say that realtive contrast.
PQ became more puncher. White plooks whiter, black look darker.

It is purely from my feeling.

How can i say ?

Seeing is beliveing.

I guess less video noise and interfernce contribute the differnce.

Thanks !! Beuceko.


I enjoy sea fishing and mountain trekking as well as watching movies and listening music through home theater and audio system.

Hi! dmusoke.

OPPO 95 has linear poweonly for audio section. video and control sections are supplied by SMPS.

Mine one supply all sections with linear power.

Well that part of it leaves me skeptical. I mean I can look at a black window from a calibration disc and there is no noise in it it. It is nothing but black pixels. You can't get darker than that.

And I can look at a Luma Zone Plate and it is perfectly clean. If there were noise or interference in the whites or blacks that would show up in a chart like that I would think.

Ah well, the important thing is that you like what you are seeing.

On topic....
So what you are saying is that the original disc with HD-DTS codec WILL play on the Oppo

I just meant that you probably shouldn't mention where you get your source from on the Forum, when discussing problems with source playback on the Oppo, lest the Forum moderators become concerned. By all means discuss any playback issues.

Maybe we are talking at cross purposes here: Neuromancer was talking about mkv issues with HD audio, so I assumed you were discussing mkv playback.

When it comes to HD audio codecs, the Oppo should play them perfectly from: an original Bluray disc; an ISO of that Bluray disc; a BDMV or AVCHD\\BDMV folder of that Bluray disc and an M2TS created from that Bluray disc (subject to any overall caveats related to playing those particular containers). The Oppo generally will not play them well from an mkv container.

The difficulty is more with the container support on the Oppo than the actual HD audio, so assuming the HD audio in an mkv is not corrupt, it should be possible to convert that mkv into one of the better supported containers on the Oppo (eg M2TS) and play the HD audio perfectly.

Thanks Lee.... i didn't know the video used a switching mode power supply(SMPS) section.

I never understood the reasoning for not supporting better the MKV container in the Oppo 93. I really love my Oppo, but I end up using my cheaper Dune B1 more since in handles MKVs flawlessly over my home network. Oppo tech support suggested as you stated the M2TS container, but I lose my chapters with such container.
FWIW, I can still watch my MKVs in the Oppo but no lossless audio...
One day maybe, Oppo will see the light... Til then I'll keep my fingers crossed.

Bob, do you "believe" that eg a Wireworld HDMI cable delivers a better contrast than a eg supermarket HDMI cable.

I think personally that watching piece of a film is more informative......it is the same in digital audio....measuring the zeros and ones....you cannot get them more acurate but ultimately its the ears that tell you sometimes different in this case the eyes.

No, I do NOT believe two HDMI cables can deliver different Contrast unless one of them exhibits flat out signal errors -- which, in the case of HDMI are going to be both objective and obvious. It's no different than people claiming an expensive power cord for the player produces inkier Blacks. Just mumbo jumbo. You CAN'T GET darker than whatever your Display produces when handed the numeric value representing a Black pixel. The data transfer results from an HDMI cable are either correct or wrong. There is no "better" between two cables that are "correct".

It would be like saying my expensive calculator adds up numbers producing a "better" result than my cheap calculator. It can't be. The sum is either correct or wrong, and there is no "better" between two correct sums.

Better built HDMI cables can have real value in durability, mechanical fit, and robustness for things like HDMI handshakes. But above some threshold, they become "correct", and once you achieve that threshold, spending 10 or 100 times as much can not make it "better". And for normal length HDMI cables, that threshold is actually pretty inexpensive.

Have you ever used/seen a Ayre DX-5 before? Much better PQ (as well as SQ), than any stock Oppo IMHO.

There are lots of things that make up subjective picture quality beyond Contrast. But I get skeptical when reports of improved picture quality tout things like improved Contrast or inkier Blacks.

There are darn few bugs in the 83 (on which the Ayre is based) affecting the digital data that goes out on its HDMI cable for any chosen content. Show me how changes you've made can fix such bugs and then you've got something. Improving a digital circuit in a way that results in the same digital output gains you nothing.

That is why I only trust my ears and eyes, and not someone else's. Bob has his views, he has that right. I have seen what Ayre has done to the Oppo 83 with better, linear power supplies. And I believe Dr. Lee enough to puchase again a Oppo 93, and buy his power supply upgrade. Over my 20 years of hearing what mods can do, and reading by "experts" that it cannot be so. I am the expert to my eyes and ears, if you will.
