I always thought you need real high powered amplifiers to get a decent sound from inefficient speakers in a large room. We just did an experiment this past weekend which proved (to me) that it really boils down to how loud you listen to your music. I have a pair of McIntosh MC2200 amps - 200 wpc @ 8 or 4 ohms, bridged to 400 wpc, driving a pair of Martin Logan Aerius i speakers. Listening room is a large 20'x20'x20', basically a huge cube. A friend of mine brought over his home made 8 wpc tube integrated amp to show off and we decided to hook it up just for kicks and see what happens. Contrary to our expectations, it wasn't that bad at all. The obvious limitation was the sound volume which was reasonably loud but nowhere near what my amps could do. The overall sound also had less "body" but it was quite listenable otherwise. Anyway, I don't know how all this translates to your specific situation but I would not be surprised at all if the XA60.8 drove the Salons without a sweat unless you listen to rock music at concert level volumes.
