I need some help and some explanation about a couple of things. I have been involved in home theater for years on a basic level but am learning a great deal from everyone here on HTF. The concept of using a receiver as a pre-amp had never occurred to me but seems to be a pretty common practice. First I have these speakers- Paradigm monitor 9's, cc350 center and ADP350 surrounds with a pw-2200 sub. I am looking at a new receiver and trying to get the most for my money. My local stereo shop recommends the Pioneer vsx-47tx which seems to be a great receiver but the price is about $2000.00. I was wondering if I would be better off going with a vsx-45tx for less money and spending more to purchase a good 2 channel amp to run the mains. I have never seen this done before. How do you hood up the amp to a receiver? If I did go the receiver/amp route what would be a good amp to use. I want to set this up as a 7.1 system. This combo is 95% home theater used and would like to make an informed purchase. Thank you for your help and thanks for this great forum.
