Modwright Oppo 105

I received my Modwright Oppo 105 today. It sounds good, but is relatively lean - and not very extended - in the bass. The sound overall is missing a fullness and organic quality that I associate with tubes as well. I have been using an Exemplar modified Denon 3910 for years, and so far I prefer it. Naturally, I am quite surprised and disappointed so far. I will be patient and put more hours on it, of course. I am very familiar with "break-in." Dan burned it in for 72 hours or more, but I have only put another 5 hours or so on it so far.

Has anyone else had this reaction/experience? Maybe it is the Electro-Harmonix tubes, and I need to try something else? I am also wondering about Dan's use of silver wiring. Thanks for any thoughts you have.

Dan is a stand up guy for sure. His customer service is the best in the industry.

Glad you are enjoying your new Oppo. Have fun rolling tubes and tweaking it.

I have the MW Oppo 83 and I have to say that what you are describing sounds like a technical issue. My Oppo sounded very full, warm, and robust with killer bass right at the start. I think you are on the right track with calling Dan as your first step. In the mean time, see if you can isolate the problem by trying different sources and seeing if there is a difference. Try different cables (both IC's and speaker cables), try different tubes, etc. Double check the initial settings in Oppo set up screen. Make sure the latest firmware is installed.

For tube rolling options, I tried the Mullard and found it to be a big improvement over the stock Russian tube it came with. The Sophia Electric had a better synergistic match with my rig because it sounded more open, extended and clear with some loss of warmth. You can buy these direct from Sophia Electric- I think they were $200 for the pair. The nos Mullards are more difficult to find, but they pop up on Audiogon regularly. They can be spendy depending one which ones you get.
