I have had Amatis for two years and I am very pleased with them. During that time I experimented with what was connected to them. As for amplifiers: I began with a Krell KSA-150, which I owned before buying the Amatis. I also tried a Krell FPB 300c, running it in Cast to the Krell KCT preamp that I bought. The Krells, especially the 300, did a good job with the Amatis, but they were not as musically involving, in my judgment, as the Accuphase A-50V, which is the amp I finally settled on. As conventional wisdom has it, the sound will depend on how well all of the components work together. It is also well recognized that room acoustics are important and will affect the sound you hear. What audiophiles rarely discuss, in my experience, is the matter of human hearing, which varies significantly from person to person -- the lack of discussion probably relates to the fact that we cannot offer many informative generalizations beyond acknowledging the fact that, yes, two people may differ significantly in how they judge sound in the same room with the same system and the same source materials. That is why you must ultimately depend on how pleased or displeased you are with what you hear, regardless of what others say.
