WOW!!! I've learned more in one thread than I have in a weeks worth of searching the net! Speaker placement was probably the interesting.
I too am in the midst of upgrading from a 10+ year old system built purely out the Technics equipment. GX670 etc... It doesn't sound too bad coming out of the Cerwin Vegas, but when I head a set of Klipsch speakers, I knew it was time for an upgrade.
I've got about half the budget being discussed here, but am hearing great ideas and methodology for determining what to get for what you can afford.
I've already bought the Klipsch RF-82's for the front. Just waiting for them to come in. I had to order them because their the wood finish. I'm looking at the Denon 3808, which I'm glad to hear via this thread appears to be a good choice. Also thinking about Klipsch's RW-12D for the sub. The rears are a pair of '70s Sansui round speakers my brother got while he was in the Navy. Being omni directional, excellent bass, and sounding so good I just can't get rid of them. Besides, they hold a lamp really well too.
Thanks again for the excellent thread! I've only been a member a couple of days. So I know I've got a whole lot more reading to do!
