A good friend of mine is willing to give me $300 for my 3 month old Pioneer VSX-D811S. I really like my receiver, but after hearing some higher end stuff, and purchasing some new speakers (after selling my old ones to another friend) i feel that now would be a good time to upgrade my receiver as well. Only problem is $$. I've been looking around and i'm pretty sure i can pick up a used Denon 3801 for around $500. I'm pretty sure this would be a solid step up, especially for $200. What would i be missing out on by getting a 3801 as opposed to a 3802? My other option would be waiting awhile and getting a Pioneer Elite 43TX. I know the 43TX and 3802 are pretty comparable, so i assume the 3801 is pretty comparable too, and a steal at $500. Also, it would be atleast 4 months efore i could get the 43TX because of $$, and by that time my friend may not want to buy my 811S. I'm pretty sure that a 3801 for $500 would be a great deal and i wouldn't regret it, and wouldn't feel the need to move on up (up might be subjective) to the 43TX. Any General comments? I'll be matching what ever receiver i buy / keep w/ JBL N28 mains, N-Center, and N24 surround and back surrounds.
