Ok what do would you buy? A Parasound Halo A23 for $529 or an Adcom GFA-5503 for $700? I'm purchasing one of these new amps primarily to increase my pleasure with stereo music, but adding some extra power to my center channel wouldn't hurt in HT application. By the way, these amps will be going in my bedroom system, not my theater system below. By bedroom system consists of two RTi8s and a Csi5. I want to make my 8s sing! Any suggestions? One last thing, these will be fed by the second zone of my Yammie HTR-5890 until I can afford to buy an pre amp from either one of the companies depending on who I choose. Thanks guys.
