My friend is looking for a good 5.1 reciever at or under $250. While poking around on Crutchfield, he and I found the Pioneer VSX-D712K reviever for $250. Well, as you know, Radio Shack sells some rebranded Pioneer stuff as RCA and we believe we've found the same reciever in the RCA STAV-4090 for $50 less. The question is whether this reciever would be better than a Sony model he's considering, the STR-DE595. One major difference I see is that the RCA/Pioneer model features binding post terminals on the back instead of spring clip terminals, and I think that makes a big difference when it comes time to hook up speakers. So, it it better to go for the Sony or the Pioneer/RCA?
