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
