Krohn-Hite UF-101's?

So I got a pair of these last week and I'm wondering what to expect from them. Anyone have these? Comments would be highly appreciated since I won't be running them until the late fall due to the extra heat they make.

These have fantastic specs but I was told elsewhere they achieve those by using lots of feedback and some other tricks that make them sound bland. They came with a pair of QUAD ESL-57's which I was hoping would be a match made in heaven.
 
I believe that this is one of the few amplifiers that uses the McIntosh Unity-Coupled output configuration.

This is an ultra-low distortion tube amp. If you are looking for a colored sound from this amplifier, I don't think that's what you will be getting. They claim .0015% distortion at 35W.

Again, this is a great amplifier, but I wouldn't expect it to sound anything like an SE 300B amp. It's going to have a very low Zout and practically no distortion.
 
The thread title rang a bell and now I recall looking for one of these amplifiers back when I got into tube/hifi (tube guitar amps before that), around 2007. I think I had some wild idea about building no-NFB push-pull amp around those output transformers.

Nice score
