ATI was formed by Morris Kessler, he owned SAE way back when. ATI also builds amps for other companies...Adcom, Outlaw Audio...and a few others.
Is there a very nice SS amp around 1K?
Adcom 5802 300 watt powerhouse that runs in class A under normal listening. It is a 50 pound beast. It was just recently discontinued from its 1998 introduction. Lots of positive reviews.This was part of a high end endeaver using a Nelson Pass design. Used around $850. Can't do much better for the dollar!!
