Focal 906

If you are turning it up any decent amount, or listening to stuff with some substantial bass content, I'd be willing to bet you would greatly benefit from more power.

Keep in mind, those 906's sound best pointed almost straight ahead, with almost zero toe in.  You should get incredible imaging that way and a gigantic holographic soundstage.

I have some relevant experience here.  I was running the Aria 906 with a 50 wpc integrated amp (Rega Brio), and it sounded very good.  However, on really dynamic peaks the amp seemed to strain a bit.  There was some congestion or peakiness to the sound.  

I now have them paired with a 220 wpc integrated (Musical Fidelity M6si), and the difference is significant - no more strain.  The music just sounds open and relaxed.  To be fair, the M6si is three times the price of the Rega, so it should sound much better.  However, I think it's the extra wattage that really makes the difference.

Hope this helps, Scott

It does ... Thanks Scott!!

Thanks Contuzzi !!

No problem.  The 906’s are startlingly good speakers when set up right.
