At first I was trying to decide between a Denon 3803 and Pioneer 45tx. And then yesterday I did something that is completely foreign to me...bid on a used amp on ebay. I now own a Carver AV-705x THX 5 channel amplifier which is shipping to me today. I am definitely in over my head and need your help. 1. Do I still buy a receiver or are there pre/pro's out there that are just as good for the same or less money? 2. How many and what king of cables will I need if I start out at 5.1? (I currently own one pair of audio interconnects) 3. How do I test out the amp when it arrives to make sure everything is functioning properly? 4. How do I explain to my wife that we still need another component to make everything run!?!?!?!? Thank you in advance for any advice you are able to provide to get me back on track.
