My experience was that their newer products were not as good as the older ones, although the Solo was a terrific product at a modest price point. I still have one of the early Power Blocks. I tried out one of the newer "III" versions that was "passive," where the selling point was supposed to be that they did not limit current. Well, I went back to the old isolation transformer-based unit in a New York minute. Truth is that most power amps don't like conditioning of any kind, and current limiting is not relevant on anything other than an amp. He was chasing a trend, and that's ironic for the guy who started the whole power conditioning trend in hi end audio. Tice also made some really good cables, too.
