Amplifiers:A Keeper for Life. Do you know of one ?

I sold the keeper. I thought the CAT JL2 was a KFL, but when I heard the Atma-sphere M-60s on my system with the Merlins that are very OTL friendly...well the CAT is gone. I still think the CAT will sound better with more speakers, but if OTL can work with your speakers it is very special indeed. Now if you have a CAT, there really is no reason to think of something else, except for the fact this hobby doesn't isn't really a hobby if you keep anything for life.

The Zanden 9600 monos.

Hi Nil,
Agreed!

Wolcott CA-250 industrial-use monoblocks.

I would add the Lamm 1.2s or M2.2s on the list.
One of the best I've heard.
