I owned the 0's and 2's and heard the 3's and 1.2's in other systems I know well. They all sounded great. The problem with the whole series of power amps was that at every power level they drew an enormous amount of power from the wall, and produced an enormous amount of heat. By the time I felt I needed the output of the 1.2's, I also felt they ran too hot, drew too much power, and were too heavy--oh, yes, they also had the off-on switch on the back to make it worse and discourage you from turning them off. But the sound quality on every pair was superb and very similar, given their power limitations.
Aleph Owners and Users...
Are there sonic differences between the different Aleph models (i. e., 0, 1.2, 3, 4 & 5)? If so, what is the best sounding amp. of the bunch, and why? Why were the 0 and 3 the only Stereophile Class A amps? What about the 1.2, 2, 4 & 5s? Does it relate back to sound/performance vs. the other models? Which Aleph model is the best overall? Does anybody have a recommendation on an Aleph model vs. an ARC V100 mkII? Thanks for the help.
