OPPO 105D with EVS mods

This is the Swiss Army Knife of digital playback.  This BDP105d was bought and picked up directly from Oppo in Mountainview Ca. This is my third Oppo and all have been awesome, trouble-free machines. This one has been upgraded with EVS stereo board mods, the disc tray mods and removal of the toslink fiber optics to further improve the sound. The unmodded Oppo sounds quite good but the upgrades pushed it into another class. Far more resolved and quick with much more solid bass, lifelike mids and well defined highs all the way up. Please research the EVS mods done by Ric Shultz if you are not familiar with his work. He is a great engineer and a consummate audiophile. Again, this unit has worked flawlessly for 4 years with these mods. A description of his work is further down in this ad. 
The player is fully functional.  I never really used it for more than stereo audio playback but the video and multichannel work perfectly.  The top has some minor rack rash. The face has a corner on the right that does show when looked at it face on (pictured) but not a horrible blemish. That is why it has been rated a 7/10. It comes with the original remote, WiFi antenna and the usb extension cable for the antenna, all fine working and appearance condition. Original unit cost $1300.00 and the mods were $850.00, both incredible bargains.  Buyer pays: Actual shipping cost.  PayPal included in price.  Local pick up in San Jose Ca. Ok. Listed below are the mods as described from the EVS website:  

Mod to 2 channel output board:

1. Change all 8 power supply diodes in the analog linear supply to great sounding soft recovery diodes.  This makes the sound more detailed, 3D and more musical.

2. Add two WA Quantum capacitor chips to the two large power supply caps in the analog stage.  Way more real and detailed.  Add four more small capacitor quantum dots to power supply caps.

3.  J-fet buffer output stage for both unbalanced and balanced outs:  This zero feedback j-fet buffer output stage is super, super pure sounding.  This output stage uses our hand made cascoded current sourced shunt regulator system.  Only one fet in the signal path.  No I-V converter, no op amps.  There is just one resistor, one j-fet and one coupling cap in series with the signal.  The resistors are super world class (better than any resistor I have ever heard).  The coupling cap is a JB JFX polyprop cap with a WA Quantum dot on it and it is bypassed by my modified Wima .33uf polyprop cap.  This output stage is more sonically pure than anything anyone else is doing, including tube/fet stages.  The only downside of this output stage is that it puts out just 1V RMS per phase.  If you have a preamp then you are fine.  However, if you are running the Oppo straight into an amp or into a passive line stage then you might not have enough gain.  The loss from stock is 6db.....maybe a couple of o'clocks on the volume knob.  This mod gives you modded unbalanced and balanced outs. 

4. Add a WA Quantum Semi conductor chip to the two channel DAC.  More detailed and real.

5. Change 4 capacitors on the DAC power supply to better caps including 2 modified .33 Wima film caps and also add one WA Quantum chip to one of the caps.  Cleaner and more focused and real.
 
6.  Change the DAC clock to low jitter femto clock.

7. Damp regulator heat sinks for way more palpable sound.

There is $98 worth of WA Quantum chips added in this mod.

Mods to the disc tray

 Black the underside of both CD covers and all around the laser assembly with flat oil based paint.  This makes all discs sound warmer, more musical and cleaner.  Damp the disc clamp with constrained layer damping material.  This makes the sound cleaner, clearer, faster and gives a better tonal balance. Damp the disc clamp holder and the transport cover with constrained layer damping material.  Way more natural, pure, detailed and real sounding.  Apply AudioMagic Blackout Paint (damps and shields) to the CD tray and then paint over that with conductive black paint.   Cleaner and more real.
