oppo 105d straightup

Hi Digsmithd, can I suggest you try this as it wont cost anything, and it’s usually for the better, by removing the ModWright's preamp section out of the equation.

Feed the output of the Oppo 105 direct into the ModWright's HT bypass rca's (Also function as Preamp Inputs)
And then use the volume control of the Oppo's remote as your volume control, this removes a lot of unnecessary preamp electronic from the signal path.

A little more info on how it's done if your not up to it from ModWright.

"Right button is HT/BP (Home Theater Bypass – Also acts as preamp input). When this button is pressed, input display will read ‘bp’ for ‘bypass’ and volume display will read ‘--‘ This will bypass the preamp section of the Integrated Amp and feed whatever source is connected to HT/BP RCA inputs, straight to the amplifier, with NO ATTENUATION OR VOLUME CONTROL. IT IS RECOMMENDED THAT THE HT/BP INPUT ONLY BE CONNECTED TO A SEPARATE PREAMP OR A PREAMP/PROCESSOR FOR HOME THEATER USE.
· Right control knob rotates freely. Turning knob in clock-wise rotation will increase volume from mute = ‘- -‘, numerically from 01 – 99. Remote control may also be used to adjust volume. Volume level is only displayed on digital display.
· Left digital display will indicate inputs as: CD, L1, L2, L3, (P1, P2 if phono option installed), (D1, D2 if DAC option installed) and ‘bp’ when HT/BP button is depressed. In fault mode, left digitital display will read ‘00’ and right display will read ‘P5’."

Cheers George

I'm using a server and Antelope DAC for CD and high-res storage, but needed a universal player that just does the job. The 105 serves that purpose. Second that "use the XLR's" comment.

You've heard some good answers...namely: for the price it does a good - very good job versus your system's level of sophistication. As for single box CD players you will probably have to add at least 2X-3X its price for a better stand-alone unit. On the other hand you can take that extra $$$$ and put it into one of the latest great value stand-alone dacs and use the 105 simply as a transport (which is what I have it for) and the overall sound quality vs. $$$$ spent is now excellent while all its other [numerous] abilities are icing on the cake; just keep in mind the added cable can tend to throw this equation off a bit, depending...
Also very significant: their warranty, customer service, and reliability are all very very good: an important point.
Enjoy.

Gotta comment on Cdrc's blast at the ModWright modifications. I know the OP doesn't want to modify the 105 and that's fine. But the Modwright tubed output and separate tubed power supply takes this good machine to a different and much better sounding level. Too, dealing with Modwright has been a pleasure. My Oppo developed a problem -- an Oppo problem, not ModWright's -- that required a new faceplate and ModWright handled the whole thing painlessly. I couldn't be more pleased with the Oppo/ModWright experience.
