Modwright Oppo 105

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.

Jfz I have the Modwright Sony 5400 and am using the Sophia tubes in the player and the Create Audio 5AR4 in the power supply. I replaced a RCA (Mullard) with the Create tube in the power supplay and like it a little better than the RCA. I have used Vingage Tube Services in Rockford, MI. in the past for tubes with excellent results. It sounds like there is an issue with the player.

Hi, this is Dan Wright. I know exactly what is wrong, as I sent out two units on the same day, your unit and one that went to Seattle. I DID wire them both out of phase in one channel and this is EXACTLY what you are hearing.

I guess I was having a bad day...sorry, human after all... ;).

I will arrange to have the Player Only, brought back to our shop IMMEDIATELY, on our account, and resolved for you promptly. The way to prove that this is the case, and hear the player as it SHOULD sound, is to reverse the polarity in ONE of your speaker cables. Either amp or speaker end, just swap black and red leads. TURN OFF AMP FIRST!

I am certain that this is the case, as the two units were worked on by me PERSONALLY and shipped on the same day! I didn't catch it as I was listening for something else and it was a VERY busy week.

I sincerely apologize for the inconvenience and I assure you that this will be resolved promptly and completely at our expense.

Sincerely,

Dan Wright

The Oppo's are more on the lean side for starters and the Denon 3910's lean towards a warmer mid. I think the Oppo's are much more musical and revealing vs. 3910, 5910 Denon's which I own.

A couple of very good RCA Grey glass 6NS7's will warm up the mids but won't do too much for the bottom end. If you have a lean mid and not much low end snap and punch you may want to look at a polarity problem on the Oppo as well. Just a guess here but it can't hurt to have Dan look into this.

It might be a good idea to wait until you have logged about 100 hours on the Oppo before making any decisions about sound quality, which can vary considerably beforehand. I ran my modded Oppo 103 in on the XLO Test CD burn in track for a few days before listening to anything. noto bene - The Oppo responds very well to WA Quantum Chips - capacitor chips, fuse chips, semiconductor chips.
