My current set-up is a Luxman AX590II, full class A with the 30.2's Sure, a little more power would be nice when I'm cranking the Stones at 100db, but I don't do that much and even then, it's an amazing combination. I had them with a McIntosh amp/preamp but that was not a good match. Mushy is the best I can describe it. So lots of power is not helpful unless it's really good power. Hope this real-world info helps.
