Day 2 went very bland and dark for some reason. Figured part of it might be the reseating of the MC-05’s. Had not touched them for around 1000 hours. Anyway, got impatient tonight and treated most of the rest of my system . IC’s, HFC RCA phono destination adapters, amp to speaker bananas. WOW...in 5 minutes of all tube warmup, the difference was remarkable. The midrange and highs are right there, very clear,but not fake or analytical . Finally, as someone who very humbly has a lot of experience with live, acoustic music, my only complaint at this early juncture is a skewing of the tonal signature slightly away from richness to lean. But again, we're only talking about Day 3 and I'm excited to see what happens in the next few months.
