does anybody own any Parasound Halo gear? Have you auditioned any halo gear? Can I get any feedback on the products relative to other gear that you have auditioned? I currently own a Denon 4802 that is driving B&W CDM NT series and at near reference levels with all channels driven, the AVR is shutting off... apparently the load is too much... I'm really interested in getting the A23 to drive the mains first and offload some of the responsibility that the 4802 must handle right now, adding the A52 in a few months, and eventually upgrading to the Halo C2 or Krell Showcase... any feedback would be welcome?
