I find the discussion of the hybrids vs the OTL's an interesting one. I too heard the Hybrids and the OTL's at Bill's house on two different occasions. Give all the hype regarding the hybrids, I was underwhelmed by what I heard. I was expecting the Holy Grail and I was disappointed to say the least. While they had all the slam you could want, I did not find them very musical especially when compared to the Lamm ML2. My wife shared my opinion regarding the amps. For my tastes, if it came down to a choice between the hybrid and the ML2's, on that particular day, it would have been the Lamm's. That is really surprising to me as I usually prefer high powered amps over lower powered ones. Oh well, to each his own.
