Are Pass Labs amps probably the best ever you can buy ?

Pass will Pass but others wil to. Try as many as you can and try a Hegel if you have the chance. I have heard them only in an audio Show setting. As a tube gear owner I put this sollid state Amp on my check it out in my system list. In my network there is a buzzing about Innamorata AMPs. They are all tube lovers that have no objective to sollid state but Sollid state gear has to be "alive".  What that means is to subjective and a matter of taste. Only your ears can judge. Great to have such a budget at hand...many options. Don't settle in to soon and have fun.
