Apparently this thread has taken on a life of its own ;). I have not had nor taken the time to read all of it, but I gather that things got ugly at one point.
Regardless of all of that, I just wanted to clarify and update information about our Denon mods as I have not been very good about releasing information. We have just honestly been buried and I have been finallizing the mods.
We did take a solid-state modified and a tube-modified Denon 3910 to CES and we auctioned the tube unit. I believe that 'Smilin' won the auction.
I do not foresee us offering a volume control on this unit at this time, remote or otherwise. Unlike the Crystal chip, the Burr Brown chips do not have an on-board volume control (I don't believe) and I don't have a good R/C solution for adding a volume control otherwise.
Our Solid-State mod is NOT just a parts upgrade and op-amp swap, but rather is a re-designed analog stage. It is quite good and offers an option for those who are not tube-inclined, for Class A performance.
The tube mod will likely ultimately have an outboard power supply. I have built the first unit with internal supply, but am not satisfied with the installation due to the weight of the 'iron' used and the strength of the chassis. I also believe that getting the high-voltage supply outside of the chassis is superior sonically. We are using toroidal transformers, so EMI fields are not so much the issue, but there are other limitations here in my opinion.
I will be finallizing the CES unit for 'Smilin' and I am sure that he will post his impressions.
For the record, I hope that we all remember that this is about the music and bettering our enjoyment of it. Alex, John, Allen, Richard and I all do good work and have taken different approaches to the ultimate goal of superior music reproduction.
Enjoy the music!
