I use a Harmon\Kardon reciever, with JBL speakers and a Sharp projector. All of the peices are roughly 10 years old and still look/sound good to me....
I know none of my ish is audiophile quality; however, it is all top end comsumer level, and it's paid off.
My next move will be to a DLP projector.
Get a 3 chip DLP projector, then you will be set for another 10 years.
