First, I appologize if this has been covered a lot, but I could not find a recent post about this and I know receivers have come a long way. My specific question is are there audible advantages to having a 2 channel integrated amplifier versus a good 5.1 a/v receiver? I love music and bought a Cambridge Audio Azure 840A integrated amp and 840C CD player. Unfortunately, I can't watch concert DVD's recorded in 5.1 or stream any music from my computer without additional equipment purchases. I do love music, but am not sure I am the most critical of listeners compared to some. I'm wondering if I should replace my 2.1 channel integrated amp for a high quality a/v reciever.
