I have an Aleph 4 (100w/ch in one large box) and love it. Its the truest sounding amp I've owned so far. MGottlieb is right, though, they really use a lot of power and generate a lot of heat. Its no surprise, they run "pure class A", no switching power supplies or other gimmicks to achieve "sort of class A". Thats why they sound so good. They are essentially a 2 stage triode design with lots of output transistors in parallel to get 100w (in the case of the Aleph 4). I just bought a small whisper fan and all is well.
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.
