Mark Levinson 534 compared to Pass 350.8

Has anyone heard these two amps?

Any thoughts comparing musicality, dynamics, holographic qualities and jump? 

Any thoughts would be greatly appreciated.

Best amp I ever had was the VTL 200. But I bought it as a demo and if I called the company

I was treated with complete contempt so I realized it would not work in the long run if I had any problem and it needed to be fixed.

But that had everything I wanted if anyone has heard it.

Looking for that warmth and musicality in a solid state. 

My pre is the ARC ref 10 which is not going anywhere.
