Revel Ultima Solon 2s w/ Pass Labs amps

Everything depends on your room size and absorption characteristics, and how loud you like to listen.

The Salon 2s are rated at 86db/2.83v @ 1 meter. If you like to listen to music with peaks of about 95db at your listening position (loud, but not overly so), and your listening position is at least 10 feet from the speakers (typical for Salon 2s) you're going to find the peaks at 1 meter will be in the range of 8-10db higher than at your listening position. So let's assume you need 103db peaks at 1 meter from the Salon 2.

If 86db at 1 meter takes about 2W, then 89db takes about 4W, 92db about 8W, 95db about 16W, 98db takes 32W, 101db will take 64W, and 104db will take 256W. So as you can see with the Salon 2 it is very easy to project needing at least 250W/channel. If you like listening to relatively loud music in a large room you might need easily need 300W/ch. That Aleph 1 will get you to about 98db at 1 meter, which might sound okay in a modestly sized room, but you're not really hearing what the Salon 2 is capable of.

I'll second what your dealer and Tmsorosk said about the Salon 2s coming to life with 300 watts of power, especially in a large room. I'm using a Plinius SB-301 to drive mine (310 wpc into 8 ohms and 470 wpc into 4 ohms, so around 400 wpc at the Salon 2's nominal 6 ohm impedence).

While I seldom turn the dial past 11 o'clock, these things with their six woofers absolutely gobble power and will dive deep into an amp's reserves even at less than ear-splitting volumes. So while I envy your Alephs' Class A output, I do think Salon 2s would be a bit watt-challenged with them.

Oops, I just noticed a math error from an edit I did. 104db would only take 128W. Still, 107db isn't extraordinary at one meter in a large room, so the 300wpc recommendation is still valid.

I had 300 watts on the Salon 1 and found it needed more. I then switched to 700 watts and found it a better match. The room I had was a little large and I listened at a high volume (not ear bleeding).
