What is the best solid state amplifier you have ever heard?

I’ve had Krell KMA-160’s and Pass 250’s (I think those were the ones) and now have Krell EV 600’s.  The 160’s was my first experience with pure class A bias amps.  I .loved them, but just didn’t have enough power.  I was pushing Martin Logan Monoliths and wanted to get a beefy tube amp for the screens, but ended up selling the speakers here on Agon.  I bought a couple of demo Max II’s and used the Pass Labs for them, but ran into the same problem.  Thought about going to tubes, but learned they would be too much $$, for the power I wanted.  With the EV-600’s, I can find no fault.  I’ve never seen a review of them here and bought them used from a fellow Agoner and love them.  To me, there’s nothing like a class A amp.

Don’t be cruel but I’m an Integrated  Mcintosh fan. Built like tanks, my last
unit was 36 years old and brought good
money when I did the upgrade. 
Just love that warm un-fatiguing sound. 
I think with amps at a certain price point you’re really splitting hairs.
Now speakers are another story.
It truly is one of the most enjoyable hobbies out there. 😎

I believe the speakers have influenced my opinion but the best I’ve heard (so far) are 
1.  Burmester. Precision & detail 
2.  Soulution. Musical with detail. 
3.  T + A.  Musical with depth and precision. Prob my favorite of the 3. 

I guess momma really doesn't need a new car. Haha
