1. Another receiver you might want to look at for a great price
is the HK520. I just got mine and this thing weighs a ton. It is available at onecall.com for $530 shipped.
2. i can't find the URL to the site at the moment, but it lists
many receivers and their "true" power output under various conditions. i will try to find it and post it later.

3. JohnK - are you saying that receivers have minimum influence on the quality of sound? i would think that speakers/acoustics would have the most, but from what i have read recently, many suggest that receivers influence heavily also.
