HD format wars is discussed in the source components thread I believe. Now back to BA topics. Just added a second vr12 to the rig. Dual vr12's seems almost overkill but I'm lovin' it. I changed my setup(for now) to 6.1. The greatest number of discrete channels you get from non hd formats is 6.1 anyways (DDex, DTSes). I have my mains, set of surrounds, single rear surround, and dual centers. I used a y splitter from center preout (m,f,f) and connected to two of the amp input connections. Then simply wire out to the centers. Awesome. This use to be quite popular w/ Yamaha recv'r owners.
