After fearing for the worse going from my Classe amps and EAD Encore, I have to say that I am really impressed with the AVR 507. My initial impressions are that the amp has solid power, it sounds a bit more forgiving than my separates and so far for a brand new out of the box piece has pretty nice characteristics (and I haven't even setup the unit well). I will post more subjective comments once I've had a chance to live it it over the weekend and also let the receiver break in a bit. There is life after separates!!!
