Sorry for the delay in response (still trying to figure out this new audiogon interface), and thanks for the positive comments. I have really been a tube guy for 20 years now (going back to my high school days, if you can believe that), so trying the SL Kraft 300 monos was a big step. Prior to that, I had been running CAT JL-1 monos, which are still among the top 2-3 amps I have ever heard. However, Ken Stevens noted that if were to have to live with any solid state amps, the SLs would the top of his list - so I gave them a shot. The SLs have not disappointed, and are one of the few solid state amps I could tolerate in the long term (others including Constellation and Lamm hybrids). While I am a fan of the Odyssey amps, the Kraft 300 monos are a huge step up (as Klaus from Odyssey noted when he listened to them before sending them out to me, "holy f'in sh!t").
I hesitate to offer too many comparisons re: Bryston and Simaudio, as I don't want to comment negatively on what are pretty solid brands. In fact, I owned several Bryston amps back in the day, and have heard the 28B SSTs on a number of occasions. However, suffice it to say, they are not in the class of the SL Kraft 300 monos, which have warmth, dimensionality, expansive soundstaging, and that fragile tangibility in the treble, in addition to the normal solid state strengths.
