EVS modified Oppo 105D

I sent my Oppo 105D to Ric Schultz of EVS for his all out mod including his basic mod package, new low jitter clocks, an Audio Magic Pulse Gen ZX installed on AC input, J-fet buffer output stages installed on balanced and single ended stereo outputs and center channel out and new linear power supply.

The unit was well broken in before sending it to Ric. The modified player I received back is much improved in all areas including sound stage, detail, separation of instruments, etc. Blu ray video is sharper with better color saturation and depth.

I play 2 channel and multichannel SACD and DVD audio disks, red book disks, blu ray audio only and blu ray video. All are improved. I am hearing details in some disks for the first time - fingers sliding on guitar strings, very faint bells and cymbals, etc.

I feed my Epson 8700ub projector directly from the Oppo. Analog audio is fed from the Oppo to the single ended multi channel analog inputs of my modified Onkyo 5508 prepro. All processing is done in the Oppo as the prepro is used only as a multichannel analog preamp. Other digital sources are fed directly to the Oppo through its two HDMI inputs.

I use Dunlavy IVs for left and right front channels with a Dunlavy IVA for the center. All three Dunlavys are driven by Odyssey stratos glass ceiling monoblocks. I consider the Dunlavys to be the weakest link in my audio chain.

Check out Ric's web site at tweakaudio.com or just search for EVS Audio. He is very easy and interesting to talk with. He does custom modifications of Oppo players and other equipment and is developing a line of open baffle planar magnetic speaker kits.

Lissnr, I do the same thing with a Cambridge Audio 752, which uses the Oppo's mainboard. Its transport only, feeding my 2 channel system via the RCA coax output.

My experience is, you can still get gains in sound quality by cleaning up the power supply that feeds the digital mainboard boards. I use a custom LPS from Oppomod.com and I disconnect and remove the audio board.

I have also heard the Oppo transport can get more performance with a clock mod. I have not done this but will be in a few weeks.

EVS does all this, they now have their own custom Linear Power Supply, and can do a mainboard only clock mod, while ignoring the analogue audio side of things.

Yes his mod pictures look like a dogs breakfast. But I guess it's the performance that counts.

I think his issue is he uses copper wire sheathed in cotton as the connecting links. So it does not look very clean.
