Which amp

Curious as to what other listeners think I should try in my system as far as amplifier goes. Many people I read bash krell amps that are more affordable but I believe there are so many factors that can skew ones view of a particular setup including cableling. I've heard classe with Thiels and thought whatever.(prolly the room and not even the amp that made me feel this way) Thinking pass,bat,ayre, heck bigger krell? Perhaps that's all I need a bigger amp with more output. Thanks I answered my own question.LOL
Thanks, Should be plenty of good models to choose from here.
Even though I have 150w with my current amp going into my spks it controls the drivers well, When I get into louder vol levels I can tell that it strains however
