My Marantz 5.1 receiver died a couple of days ago so now I got to make a decision. I need to get a receiver to play music from my Mac via iTunes and want to get the best sound that I can for under $150. I have an opportunity to get an older AVR 3801 or for $20 more, a refurbished AVR 391. This will just be used to play music from my computer so I don't need HDMI - I just want the best sound possible. My understanding is that the build quality is quite a bit better than the 391. Will the 391, being a newer receiver sound better than the 3801? Any suggestions that you have would be appreciated.
