I am currently evaluating the 3910 mod. I purchased the Ultimate and sent Parts Connexion my 3910. I have finally let the unit burn in for 200 hours as Wally recommended. So far I am disappointed. The upper bass is overly pronounced and the overall sound isn't open. Vocals never come alive - low level detail seems obscured maybe because of the overly warm upper bass. I am AB-ing the unit with a Benchmark DAC-1. I will say that I don't remember the Benchmark sounding as good as it does now. The mod replaces the clock which Wally claims improves the digital out. I believe that has made a large difference. I have ordered some NOS Mullard 6922 tubes which I'm going to try in the unit next week.
