I myself own a pair of Revel Salon speakers. I have demo'd alot of amps for these too. Ill give you a good rundown as I have alot of experience with alot of the amps you have listed since I used to be a dealer for many of the products above a few years back.
1. Proceed: Has the ML sound, but build quality is VERY SUSPECT. Very poor soldiering joints, alot of corners cut internally. There are way too many amps in this price range that are better built, so skip this discontinued piece.
2.Levinson 431: Plenty of juice, but am not familiar with durability yet. Sounds as good as the older series it replaced no doubt. Plenty of power to drive Studios.
3.Roland: Good amp, good dynamics, will push the Studios to moderate levels cleanly.
3. Pass labs: Any of the pass labs amplifiers will do a great job. Even the X150 has a ton of dynamic headroom that far surpasses its rated output. You cant go wrong with any of the. An x250 or 350 will do a great job.
CLasse: Im not a fan of these but power to drive Studios isnt going to be a concern, though I dont think they match up as well. Top end is definetly forward sounding to say the least.
EAD: I have no experience or knowledge of this product.
COnsiderations: go to www.audioadvisor.com check out the STEAL they have on a pair of Aragon Palladium monoblocks. $3000 for the pair. This is a steal and its basically accomadation price that they are selling these for. They normally list for $6000 for the pair. Aragon amps are very similiar in sound like the Nelson Pass X series amplifiers. I would put the Aragon Palladiums between the x350 and x600 monoblocks from Pass labs at a fraction of the price. THe Aragon's put out 400 watts at 8 ohms(125 watts class A operation, over 125 watts they auto switch the bias to AB), a real world 6-800 watts at 4 ohms and over 1000 watts at 2ohms. Headroom is awesome with them. Midrange is such a great match with the Revel's too, and the bass is tight and articulate. If cost was no object and I had a choice between the Aragon monoblocks, the Pass labs x350 and the x600 monoblocks, I would choose the X600's first, with a close 2nd going to the Aragon amps with the x350 taking last place(a close 3rd in all honesty too)of the bunch. But when talking $3000 vs. $5-6k( I had the money to buy x600's too, but knowing first hand the real world performance of both units I took the extra cash saved and RAN to the closest travel agent, no kidding) and up its a no brainer. The Aragon Palladiums are a no frills industrial quality made amplifier monoblock set. If your ever in the area you should stop by for a listen. You wont be dissapointed.
