I have gone through a number of high power high amp solid state amps over the years and for the last 15 years I have been using Plinius, Went from their SA-250 Class-A to an integrated 310 watt Class A-B last year and the clarity and response are amazing. Using it with Watt Puppy 8's and my old NHT 3.3 at times.
Plinius make amazing amps.
