Hello, I am somewhat new to this forum but I have dipping my hand in HT for a while. I have two questions. 1. Is Virtual Matrix 6.1 sound any different from basic 5.1 or is it just a marketing gimick. 2. I am looking for a small 2 or 3 channel amp for my apt HT. I just want to push my front L and R or all three front speakers. Any suggestions?
