I've purchased the following 5.1 speaker system: Swan Diva 2.1s, C3, and R3s, with an SVS PB10-ISD sub. What receiver do you recommend for these speakers in the $500 range? It will be primarily for home theater. I'm looking for something that is also easy to set up and use for novices. Any comments about: Pioneer VSX1014TXK Yamaha HTR5760 Marantz SR5400 Any other suggestions? Thanks!
