Just a message to any newbies to say, do not always trust the Denon Autosetup routine. I have the new 1906 and use a musical fidelity kw500 amp as front power amp to a Pair of Gallo reference 3 speakers with their own Sub Amp. I ran the autosetup. 1: It registered I had a centre speaker, which I don't 2: Registered I have a Sub which I don't, so my Gallos were not given any output below 80Hz 3: Got all the distances wrong on the speakers 4: Told me first that my Front Left was out of Phase and then that my Front Right was out of phase. Neither were. Don't get me wrong, once I corrected all that, it sounds great and most people on their second, third, fourth etc. etc. amp, will notice, but for anyone on their first amp, they might trust the autosetup and be missing out on getting the best from their system by a long way.
