ricevs,
Thanks for posting the hometheaterhifi review of the IV7. His reference amps are the BAT and Pass, which are euphonic. All the musical and movie examples he cites show more clarity/detail from the IV7 than from his reference amps. At the end, he claims that the IV7 still has a tiny bit of treble grain. This shows a lack of understanding of HF detail. The real thing--live unamped instruments and voices--can be quite irritating heard at close range where microphones are placed even at only moderately loud SPL's. Many euphonically oriented listeners say that the unpleasant HF detail is treble grain. I interpret that review as 100% glowing enthusiasm, if you know how to review the reviewer. It is still useful, and I commend his descriptions of musical examples.
As for your one customer who preferred his $14K/pr tube amps to the EVS1200, you know what I would say to that. Everyone is entitled to his preference, but so far, I have not heard anyone who did an A/B of an IceEdge 1200 AS1 amp with any expensive "SOTA" amp say that such a "SOTA" amp had better clarity/information retrieval. The most informative person is zephyr24069 who didn't have the Esoteric Grandioso M1 mono blocks at the same time as his Legacy IV4 ultra, and made a judgment in retrospect that they were comparable. But he said that the Esoteric A-02 stereo was warmer. So I'll go on record here and say that nobody has yet heard any amp of better clarity/detail than the best implementations of IceEdge 1200 AS1. The highbrow types that own and dealers who sell, uber expensive amps would never submit to an A/B with a cheap great class D amp and report the results in an unbiased manner. Their egos and businesses are at stake.
