I have owned the AV8003 for a couple of years now and besides sounding great, it has never given me a problem in any area. Knowing Marantz, the AV 7005 will probably be a great piece as well, BUT it is a Receiver, as opposed to separates - The AV 8003 lets you choose your power. - I am running a 7.2 system with Sonus Faber speakers so I need plenty of power and for that I use KRELL - The Krell and Marantz make a great match. Now to be VERY VERY Critical - Theater is killer Killer Killer - But it falls short for 2 channel Audio - it's good but not tip top Audiophile quality - If that is a concern...Probably could run a 2 channel preamp with a Theater by pass to accomplish both - But for Theater it sounds great - Again depending on your speaker demands and power - I find myself listening to the end credits because it sounds so good - Hope that helps...Tony
