Just to remind some new comers to the AVP/AVR world, that by today's standard, any AVR/AVP @ >$4,500 would not make sense unless one doesn't mind replacing it within the warranty period or 5-7 years. They just have too many things to fail now, unlike the older models such as the Denon 3805 (some may even be using the 3803 still), up to may be the 4308, 4311, or the Yamaha RX-A up to the 3060/80, as those likely could last beyond 7 years, up to may be 20 years. My 3805 and 4308 are still running perfectly. The likes of the Onkyo RZ30/50/70 (70 only if/when onsale), MRX1140 (if/when on sale), Denon AVR-X3800/4800/6800 (4800/6800 when on sale only) or cinema 40/50/70) if in the EU.
Other than those, practically speaking one would be paying more only for ownership pride, but absolutely no sound quality advantage, unfortunately, he latter is embedded in so many AV devices users mind as the saying if you say it enough times people will believe it, so those will continue to pay more for no more or even for less in some cases, only to find out their >$5,000 investment might be ready to go to the dumps within less than 10 years. I don't agree (not often anyway, at least not fully) with
@TLS Guy, but there is a fair chance that he might agree with me on this, going by the fact he clearly is someone who wouldn't mind paying for for the AV10, but he wisely (imo) settled for the AV7706, apparently was only, or helped by the offer of a very good discount lol..
