Amp for Revel Ultima Salon 2

I would just add, that even if it has a moderate watt of 280 on the ASR 2 exc, it has an insane amount of current available, which makes it able to drive 1ohm speakers and even below that with 100% control...very very few amps can do this. ASR is also extremely fast, extremely detailed, which on the Salon 2 will make your jaw drop several inches.
But if you were to buy one of the three first you named, Mark Levinson 532 should definetaly be No.1

Your observations about using the ASR Emitter 2 Exclusive with Salon 2s mirror mine about using Symphonic Line Kraft 250s. On the surface they are entirely different designs, but what they share is huge transformers and very high capacitance.

Result? Both are fast amps with big current, making them especially appropriate to handle huge dynamic swings and not run out of steam when driving big, inefficient speakers like the Salon 2s or eloctrostatics with super-low impedance values.

It sounds like your ASR provides a very similar Salon 2 listening experience to what I get using Symphonic Line Kraft 250s.

That shouldn't be surprising, as both amps use large transformers and provide huge capacitance. Result? High current that can keep up with big dynamic swings and not fall apart. Both are very fast too, and I assume that a lot of the detail you enjoy is from your amp's ability to avoid congestion and maintain a stable soundstage the same way mine do.

What is most interesting to me is that the Salon 2 performance absolutely justifies using amps that cost significantly more than they do. Kind of turns the maxim to spend the most on your speakers upside down.

Sorry for double posting, the first post apparently got lost in the ozone for a while!

BAT VK 600 will be scary good
