I recently purchased a pioneer vsx-d912 and a set of rm6700's with a psw303. I love it, I think it sounds absolutely awesome. I purchased hte pioneer reciever for around 360 or 380 dollars with a service plan. (four years for like 30 bucks) (I'm an employee of circuit city, but I swear I do actually have some knowledge) Did I make a good choice? I really like the connectivity options on the receiver as well as the sound quality, plus it's one of cnet's highest rated receivers. The Pioneer also has an automatic room adjustment feature, which is pretty cool and saves me dropping 70+ on an spl from radio shack. I just became aware that Denon makes a receiver (the 1804) that retails for five hundred bucks, but I could get for about the same price as my pioneer if I ordered it online. Is anybody on here familiar at all with that receiver and how it sounds? Will I notice a difference in sound quality if I ordered the Denon and returned the pioneer using the rm6700's?
