If the A100 is the amp I am thinking of, I heard it several times on several systems. I am slightly fuzzy on the details, as this was quite some time ago. It ran very hot, and sounded incredible for it's size and price. The only complaint I ever heard was that the output devices on early production runs expired fairly quickly. This was due to a very high class A bias, which also accounted for the wonderfully transparent sound. I don't know the brand and type of output device, but suggest you look into availability for replacements if you are buying one, as the company is out of business.
