Hi, I am somewhat new to this and have done a fair amount of research. I am willing to go as high as $7000 for separates or an AV receiver. Past experience has me leaning to separates, however, the new Sunfire Ultimate, the Denon 5803 and the B&K AVR507 are also possibilities. Given this budget, what would you do? Thanks, Barry p.s. the only installed component so far is a Seleco HT300+ and a 110" Greyhawk screen.
