I can drive a whole Audience setup for HT with an Integra 30.3, and that I would consider on the cheap. (82s, 42s, 122c) But as Mr. P said, the Audience series really comes alive with some honest power. I am currently running my 42s, which I also use as rears, in a separate setup at the moment and driving them with an Odyssey Stratos Plus, a 25 y/o Hafler pre amp recently serviced and recapped, and an OPPO 93. I am amazed at just how good these tiny speakers can be with decent power and solid speaker wire. Using Tara Prism and Tara ICs. I actually enjoy this setup more than my two systems in my signature for lower level listening.

Any of the higher end units suggested above will do the trick.
