Paul, I strongly agree.
Though I import Opera Audio/Consonance equipment, I personally use an AES AE-3 DJH preamplifier in my system. It thoroughly outclasses anything I represent. It's a rich sounding preamplifier with a lot of dynamics. If there's one thing it's not (especially with the stock tubes), it's bright, as that is the last thing I want in my system.
Mingles, I've found that the AES preamplifier does very well with tube power amplifiers. In my system, I have had some real good results with both my Atma Sphere M60 and Consonance Cyber 800, though I'd say its effects are far more synergetic with the Atmas, as they combine to produce outstanding dynamics while striking the right balance of resolving and romantic (moreso than typical for this amplifier) at the same time. That being the case, I would certainly encourage anyone with a pair of Atma Sphere amps in the market for a suitable preamplifier to put this one on your short list.
