Amplification for Wilson Audio Sasha on the cheap

Thanks for trying to assist me.
Budget is $10K for new but will look for something in the 5K mark if buying secondhand.
Prefer something old and grunty.

I do not have  a Wilson dealer as Iam in Melbourne, Australia.
So no demo can be arranged.

The preamp that I use is ME14, see specs.

Here's a big Krell in Au. I'm sure he'll let it go cheaper, offer $5.5k.

That one Krell FPB-300c is Class A? 

That one Krell FPB-300c is Class A?

Sort of, without the big heat penalty.
As it has what’s called sliding bias or plateau biasing (class-A), which in layman’s terms, means it monitors the input music signal and raises and lowers the class-A bias automatically of the output stage accordingly.
So there no wasted time and heat in class-A when there’s quiet passages, low volume or no music signal.

It plays always in Class A then, can it ever switch to Class AB ?
