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

I love my Classe' CA M600 monoblocks. They were good enough for Abby Roads Studio. They have a few years on them but hard to beat. Its a too bad what happened with Classe'. Pass does a great job. It boils down to what sounds right in your system with your acoustics. As Salon 1 Audio mentions, certain amps sound different with different speakers. That is a vital part of the equation.

I think AudioFound summed this all up nicely. Sound interpretation varies from one set of ears to another. When you get to a certain level of quality it becomes a personal form of what you like and enjoy.

I am not seriously looking for a new amplifier. I have had our ML-333 since it was new in 1995 and have no plans to replace it.  However, just for fun as a background task, I try to keep up on recent developments so that I have a plan in case the ML-333 fails beyond repair and needs to be replaced.

One of the best solid state amps could be the new Rotel Michi
