William, I have owned the Amati's for about two years. I have found that the measurements on paper of these speakers can be misleading when it comes to reality.Although the Amati's are 92db efficient don't let that fool you. They love a tube in the signal path, but more so from the preamp. The amp is another issue. I tried the Cary V-12i mono's without success. The Aamti's need power. I finally settled on the Pass Labs X-600's, however an X-350 would certainly do the trick. I would shy away from really dry and analytical sounding ss amps, as the midrange from these speakers are truly to die for and a dry amp would not let the true sound of these beauties emerge. I hope this helps.
