Before I went into tubes, I used an Accupase amp. Somewhat similar to the Stratos SE, but the SE's seemed to have much more dynamic response with a deeper bass section (as in power wise). The upper ends were similar, but maybe a little tighter with the SE's. Glass Ceiling amps are another ball game. They go much deeper and higher with a lot more force behind the the subject matter. The Accuphase amps were not colored in anyway, but the sound was darker and much less transparent. I felt the GC amps were much closer to live music all the way around. I did have a some friends over for a listen, as this would be the last word in getting it right. Two of them were in the studio when the recorded Kinda Blue, and the other guy is a well known bass player. The bassist instantly caught the strings and virtually identifed them! The two old men said it was as close to getting it right as they'd heard, but still gave it a 90% (both were reed players). I was happy! I wanted to get Mel Rhyne down here for a listen to some Wes Montgomery stuff to see if I needed to do some tweeks, but we never could get together. The two old guys pointed out that the amps seemed to get the location of the musicians in the right spot, and both said it was very very close to being right there.
