jac23 and all,
I had severe audio distortion problems (particularly noted with all types of SACDS) with my ModWright Oppo 95, immediately after February 2012 install of public beta firmware --- from a CD provided by Oppo.
Upgrading to the following March official release firmware, again from a CD provided by Oppo - while I was on the phone with Oppo tech (Dougin or Duggan) - gave same results.
I noted the former option to ouput FL/FR signals of multi-channel through the stereo DAC and stereo outputs no longer showed on audio processing screen of setup.
Also I noted "HDMI B" showed on player display at all times.
We determined that somehow my player had loaded the firmware subversion for the model 93 player. The Oppo tech implied my player must be a BDP-93 or have a 93 main board instead of a 95. I protested that ModWright does not even modify Oppo 93s and I had complete trust in Dan Wright's integrity and repeated my unit was a demo unit purchased from ModWright and sent direct to mje from RMAF Denver.
The Oppo tech insisted I would have to ship the player, including the ModWright external power supply for the tube mods and the tubes, to Oppo.
I countered that I would ship only the player to ModWright, as they would be better able to disassemble their mods and they could send the player's main board on to Oppo to get "flashed" as the Oppo tech said would probably have to be done.
I got my player back on Monday and all is well now...
below is an e-mail concerning this which I sent to Dan Wright on April 5

Subject: my ModWright Oppo 95
John Garrett left me a voice mail yesterday afternoon 4/4/12 ~ 4:32 EDT /1:32 PDT
detailing his findings re my ModWright Oppo 95. They coincide with what I was experiencing as problems
and reporting to Oppo. John may have found even more that I didn’t have the time to completely scope out/delineate.
I certainly have never opened the chassis since receipt from your contractor who shipped on from RMAF Denver.
And everything worked fine including the official release Oppo 95 firmware upgrades (from CDs provided by Oppo!)
which allowed selection of FL/FR multi-channel signals from SACDS, Blu-Rays, etc to go through “stereo DAC” and its processing chain and also selection of XLR terminals polarity.
As best I could determine all the problems started after doing a public beta firmware upgrade (again from CD provided by Oppo!)
John noticed something regarding HDMI B showing on display even after doing “Reset Factory Defaults.”
I had noticed that as well and commented on it in a second or third phone call with “Duggan” at Oppo.
This was after installing the official release firmware upgrade (following the public beta firmware) again from CD provided by Oppo. my conversation with “Duggan” walking him through the setup options showing on TV screen
We discovered the firmware SubVersion showing was for the Oppo 93, which was when “Duggan” started
questioning that the player or board was a 93 and not a 95 and our communication went downhill.
I told him I had complete trust in ModWright’s integrity and brought up that everything had worked fine after the earlier official release Oppo 95 firmware upgrades which first allowed selection of FL/FR multi-channel signals from SACDS, Blu-Rays, etc to go through “stereo DAC” and its processing chain and also selection of XLR terminals polarity
I suggested they provide a firmware CD with just the firmware components (main, MCU or sub version, and loader) for the Oppo 95
and with no firmware components for the 93 (or 83 or anything other than 95) and what they burned and sent me was a CD with only 95 subversion /MCU firmware. When that one said “No Firmware Upgrade found” and I called and asked them to send a CD with exactly what I had requested, Duggan got his back up and said “We are not sending you another CD!” and “You will have to send us your player and the power supply and the tubes.” I countered would Oppo work with you if I sent the player to ModWright as you/your techs know how to disassemble your mods properly and Oppo may not.
I hope that John can write his findings up and send them along with the main board to Oppo
(maybe even specifically to the attention of “Duggan”?!?).
At any rate it is good to get my player to ModWright, diagnosed by John Garrett (and confirming the problems I was experiencing) and hopefully things moving to get it “flashed:” or whatever and returned to full functionality.
I am enjoying music through my ModWright Oppo 83 SE for the interim.
