I ordered a pair of these (AudioSource AMP-100) to run my outdoor speaks (Moderno from Best Buy).
Arrived today. Hooked 'em up, and I gotta say, they do a nice job. I particularly like the auto-sensing feature. I have a Squeezebox Duet receiver feeding each of these, so I can fire up either or both outdoor zones straight from my phone! I now have separately controllable deck and backyard zones. Can't wait for the next summer party!
