I first heard the Zen Torii III, courtesy of a friend who brought his amp over, with my JansZen zA2.1s in my small listening room and that test really got me excited. Last night I took those speakers over to my friends house to try again in a much larger room. The JanZens are hybrid ESLs that are easier to drive than most of its kind but still in the high 80s in efficiency.
We discovered that we could get listening levels higher than I care to listen at, but going into ear-damaging rock and roll territory was not an option. OK, I am trying to preserve my hearing anyway. The sound of this amp made my speakers sound better than I have heard to date with very solid bass and super everything else.
I put my order in this morning for the amp. I have now joined the others who are "waiting as fast as they can".
