Summary: I bought from a local dealer in Lithuania. I auditioned it and liked it on the spot - classic Marantz signature, spacious, detailed and dynamic sound. I had also just purchased a Pioneer N-70A streamer (which I chose over Marantz NA-8005 for various reasons).
Summary: I think that if you are able to get this second hand or refurbished, it is well worth the try. At $450, there may be other choices. My NAD receiver was better but in terms of reliability there is absolutely no match between the two brands.
Summary: This amp comes with a separate IEC rear mains cable which needs a minimum of 6.5 cm more rear space than the technical data suggests. Before I could use it I had to invest in a right angled IEC connector; very irritating.
