I have not heard the Avatars so can't compare them to the Devores. I own the Devore 8's, not the Super 8's, and drive them with a 15 watt triode tube amp. They're 88 dB, even less efficient than the Super 8's, but the 15 watts is plenty in an 11 x 17 listening space.
More power of the same quality is always good but I wouldn't be afraid of the 15 watt output unless you've got a large room to fill. I couldn't be happier with the Devore 8's, they're the best money I've ever spent on audio gear.
