Focal 1038be or Revel Ultima Salon 2?

If you are using 100K tube mono's you would not waste your time with the Salon2 speaker: plastic caps, plastic wires, and magnesium /metal cones.
If you are looking for the fine nuance of vocal and string reproduction and passages in classical that are at times are very low volume level followed by full orchestra these don't work as reference for that..you need a nimble loudspeaker that requires little power and yet can handle a lot of power at the same time this "flexibility" is not inherent in the Revel.

I like the speaker but I'm not putting it with Audio Tekne and Ella Fitzgerald!

I have Salon 2 speakers. I drive them with a Krell 402e and a BAT Rex preamp, and Esoteric K0-1, with Stealth IC cables and Siltech speaker cables.
I work with orchestras and bands and the sound of the REvel speakers is simply a joy. They sound great in my 18 ft. square library (heavily damped) but also fill the house with sound. They also sound good off axis.I have commented before--they sound good at very low volumes (better than any other speaker i have owned) so I can listen late into the evening when the house is asleep. But the speakers and acompanying equipment are all very sensitive to the quality of the recordings. Some recordings sound awful and some are spectacular. I find that acoustic recordings really sound excellent whether it is orchestra or chamber group, or jazz and vocalists. I find the system to not have a sound of its own. I have owned JMLab speakers before this and they are just not as extended and open. I heard Rockport speakers recently that were driven by Viva tube amps and they sounded very good but not in the bass. You need slam even with classical recordings. I would agree with one of the posts about the 86db sensitivity needing a higher powered amp.

Revel speakers are from the Harman group. Owners of Mark Levinson. That will give you a pointer as to what amps they were designed to play with. 

No comparison. The Salon 2 is by far the best speaker near its price and the only reason to consider something else is poor room interaction. No knock on the focals just a different ballpark. maybe the sopra 3 vs salon 2 would get a more balanced reply's.
