You might try contacting Wilson and ask them what amps they use at shows to demo their speakers, where they'd be wanting to make a good impression. Not knowing enough to choose an amp for my Magico A3's, I contacted a VP there and found out they were demoing these speakers at shows with Luxman 509 amps. So I figured I couldn't go too wrong with a Luxman even though I could only afford the 507 model, one step down. Did the same with the speaker cables.
The Magico company's president had recommended a Hegel integrated amp for the A3's in articles I'd read, which I'd also seriously considered. But Hegels being manufactured in China, where quality control is such an endemic issue, was too big a chance to take on a big purchase.
