My setup uses a Marantz receiver too, and it's completely awesome. It is getting old though, I want to get a new one that supports all the new audio formats and has more modern ports (my current one has no HDMI). I have an Atlantic Technology
5.1 speaker setup, which I absolutely love. I am an AT customer for life at this point.
I'll post my setup in the other thread when I can get some pictures and stuff, but I highly recommend Marantz and Atlantic Technology. I have a dozen or so DTS 5.1 audio CDs that sound just spectacular through this system, like Steely Dan's Gaucho.
