I just purchased a Parasound HCA-855 from E-bay for $306.00. Quite a steal I thought. I'm using a Yamaha 995 as my pre-amp and am using the pre-outs on the back of the receiver running to the amp with acoustic research interconnects. Now, I was really excited by my new venture into seperates because I've always been told its much better. However, there doesn't seem to be any discernable difference. Maybe I don't have it hooked up right? I would figure that the volume level would change when I turn the amp on after the receiver was on but this is not the case?? My speakers are paradigm studio 40's. Thanks for any comments.
