I don't have input on either one of those receivers, but I will chime in regarding A4L. I just purchased a Pioneer Elite VSX-90 which retails for $699, for $299. It seems like a banging deal at that price with boatloads of features including MCACC pro, dual subwoofer outputs, auto sub eq!!!, wifi bluetooth blah blah blah everything except DTS:X as far as I can tell. 7 channels but I don't even have 5 going yet so whatever. I couldn't find a better deal in any other brand especially considering the sub eq feature which is limited to $800+ with Denon. Of course the question is how well does it work???
