Classe "omega" vs Pass Labs X600


I'm in the process of buying an amp for my revel salons. i just sold an omicron and am looking to either get a classe omega which I am quite familiar with and love the sweetness and musicalness of it. I got to listemn to a Pass Labs X350 amp in California and was quite impressed. Unfortunatly there is no Pass Labs dealer in Illinois where I live so I cannot do an a-b comparison. As far as set-up goes i thinks the pass labs would be easier to deal with since they are monos and can be placed next to the speaker. The Omega is 280lbs and huge so their placement is limited. Hopefully someone out their has had dealings with both. I appreciate any and all feedback.
I will leave a list of associated equiptment since it may help give an overall idea of the sound that can be represented with either amp:
mark levinson 37 transport
meridian 861 pre-processor
revel salon speaker
valhalla interconects and speaker wire
sound applications xe 12
THANKS!!!!!

Both are good choices. The Classe Omega is very powerful, clean and musical. The Pass X600 is also quite good in those areas, but does not seem to have the bass response of the Omega. The presentation is also a bit different. The X600 is a a bit more forward in the stage compared with the Omega.

It is more a matter of preference than anything else.
Another amp you might want to consider is the Edge NL-10. I use the Edge with Revel Salons and a Sound Application XE-12S, so my system is fairly similiar to your own, and I am very pleased with the sound of my system. Drives the Salons very well with outstanding bass and beautiful sweet highs with plenty of detail. I've got a large listening room and the NL-10 has more than enough power for the Salons. Not that the Pass or Classe would not be good choices as well. Each will give the Salons a slightly different presentation. Remember these are extremely neutral sounding speakers. The Edge is a neutral amp.
I think that evaluations of the fullrange dynamics is a way of making a good choice. Try to capture the rimshot or orcestral creshendo in the best way to make a quick choice. The Pass Labs have much more of that old, live feeling. But then again, you make the choice and have to try to figure out YOUR choice. Depends on your experience of music and what you want to reproduce in your home.
I read your thread with interest, as I have been curious myself of late about the Salons and just auditioned a pair this past weekend at Lyric HiFi in Manhattan. Prior to doing so, I reread the reviews of the Salon, as well as reviews of its smaller sibling, the Studio. The reason I am responding to your thread is to tell you that, for whatever it's worth, Kalman Rubenstein, a reviewer for Stereophile, bought a pair of Revel Studios as his reference speaker, and in his review of the Studio, remarked upon what great synergy they have with his reference amps, the Sonic Frontiers Power 3 monoblocks. Although all of the hi-fi magazines are capable, in my opinion, of publishing bad reviews / biased reviews, etc., my guess is that when a reviewer chooses speakers for his personal reference system and comments that they work especially well with his reference amps, there is some truth to that comment. As for the Power 3's, I don't know if you know anything about them, but my closest "hi-fi friend" has been running Power 3's for nearly three years and i have heard them at great length. I won't comment upon the sound he gets other than to say that he obviously likes what they can do, as do I, but I do want to mention that they have proven to be incredibly reliable for him -- he runs them nearly every day (and runs them hard at times) with huge Dunlavy SC-V's, and in three years, he has never had to replace any tubes. I believe that the Power 3 may now be out of production, but they are frequently available on Audiogon for +/- $4,000.

If you ARE inclined to consider Power 3's, I would not be dissuaded by the fact that their power rating is only 220 watts/channel -- each monoblock uses eight 6550c power tubes in a conservative circuit with a first-rate power supply -- practically speaking, there's not going to be much of a horsepower difference between them and anything else (you may get an extra 6 decibels or so and somewhat tighter bass if you use a mega amp, but the Salons are fairly efficient and I would bet you won't have occasion to hear the difference unless you are listening to extremely demanding material at really high volume -- 220 watts are a lot of watts if they're coming from well-designed tube monoblocks).

I could go on and on, but I suppose my main point is that, if a reviewer says the Power 3's work great with the Studios and he uses that combo as his reference, they probably do sound great together and you may want to give that amp some thought if you are looking for something for your Salons. You could probably e-mail Kalman Rubenstein for his thoughts. I could also pass along the e-mail address of my friend with the Power 3's should you want to pick his brain. And, oh yes, speaker cables ... my friend uses close-to-top-of-the-line Transparent Audio. I can't recall what Karmen Rubenstein uses -- I didn't reread the review prior to writing this. Anthony Cordesman, senior reviewer for TAS, said that the then-best Transparent Audio speaker cables were his first choice for the Salon. You would have to try them all together to make certain, but it's something to go on.

Good luck
