I happen to own the Revel Studios, but I spoke with a Salon owner who had just upgraded from the Studios and he said that while his Studios sounded great with a Levinson 250W/ch amp, that the Salons just sounded good with the same amp. He said that they really need power! (He heard the Salons at the dealer with 750W/ch Krell monoblocks and said they sounded wonderful, so much so that he immediately upgaded. I spoke to this guy because I was looking to purchase his used Studios, and we got to talking about both speakers.)
While I will not give you a specific recommendation for an amp, I will give you my advise, which is to get a really powerful amp. (Minimum of 300W/ch.) If you can afford (and have the room for) monoblocks, that is the way I would go if I were you. The monoblock design has more current and will drive the speakers the way they are intended to be driven.
For your information, I use a Levinson 200W/ch amp, and it works great for the Studios, (but then again, it has two less drivers than the Salons!)
PS I prefer the Levinson sound to Krell, FWIW.
