Compliments for my Dynaudio a42

I love these speakers. But am needing to replace my amp soon. I have a Creek 4330 SE. My cd source is too embarrassing to mention. Most of the time it's the iPod that gets listened to, unfortunately, due to convenience.

Any thoughts on a modest integrated and CD upgrade? I hear that the low impedance of the Dyn's require you not to cheat on the amp. Think I'd be disappointed with an ARCAM Solo?

Another option I've been looking at a computer based set-up, an ARCAM rDac with a MacBook Air.

And if I could get really good sound quality from the iPod w/a fancy pants dock or cable system, that's an option as well.

Hmmm....
