Hi, I'm a newbie to home theaters. I'm planning on buying a home theater setup for watching movies (40%) and listening to music (60%). Which one do you think is better: Marantz SR4300, Marantz SR5300, Onkyo TX-SR601, Onkyo TX-SR-701. Also, any suggestions for affordable 5.1 or 6.1 speaker sets? Thanks for your help!
