JAFANT - In my 20 years, we never had any Adcom in our factory. We were, however, familiar with it since many of our dealers carried it. Jim took the somewhat eccentric stance that it was other peoples' job to deliver 'proper' amplification. His job stopped at the input terminals. My assessment, at that time and continuing to the present, is that Thiel would have benefited from a more inclusive systems requirements approach. A $2000 pair of speakers is out of place, in my opinion, requiring a $10K amp to supply its peculiar needs. Jim felt that his highly resistive / non-reactive load characteristics made up for the very low impedances. But, the amp stable was severely reduced. In my opinion, many of the long-standing and ubiquitous criticisms of Thiel speakers as 'bright, in your face, aggressive', etc. are due to amplifier distress.
Anyhow, the first Adcom amp I personally heard / evaluated is the one I bought a couple of years ago with a pair of Thiel CS3.5s supplied from a member of this forum. I think the speaker needs 'better' to reach its potential, but it's better than most.
