I'm out of touch with current amps but I do know the speakers very well because I owned a pair for five or six years. They're not lean or bland by any means but something with a bit of grunt and sparkle will suit them down to the ground. I used them with both a Cyrus II and a Marantz PM66KI. They were happy with either, but they always sounded more exciting with the Cyrus. Tradeoff was the bass was less full, whereas with the Marantz the bass was fuller but overall the sound wasn't as attention-grabbing.
