I am setting up a 2nd music/ht system in my home. My other av system has a Yamaha rx-v665 (7.2) as basically a pre-amp (my mains and dual subs are run off two EP2500s).... As I am looking around for a receiver to purchase for my second system I am open to other receivers besides the Yamaha line. My new receiver will be operated in a similar fashion as the rx-v665 because the new system will be using twin ep4000s to run the mains and subs so pre-outs are a must. I have found some great prices on both Marantz and Onkyo receivers (from access 4 less) but I notice as a trend across most manufacturers that 7.1 is the standard in most low to high end receivers offered. I guess I liked the fact that my current Yamaha had dual LFE outputs for a L&R sub....with that being said I don't know if that is really a big enough of a reason to just go ahead and purchase another rx-v665? Any thoughts on 7.1 vs 7.2? Is the simple solution just to run an adapter cable out of the LFE pre-out on a 7.1 receiver which splits the signal into two LFE outputs? Is 7.2 just a marketing ploy or are there real advantages to it?
