I am definitely interested in maximizing my audio capabilities. The ability to do some of the new HD audio formats over HDMI would be important. I understand that the MA69GM-S2H can do them over analog outputs. However, the analog inputs on my pre-amp are already being used by my SACD/DVD-A player. Given that, am I correct in understanding that the new MA78GM-S2H would fit the bill better for me?
