I quite agree with that article, and I have to repeat, yours is excellent just too bad it is not accompanied by some lab measurements. Having said that, I know ADTG is fooling around with that post. Like me, he found out those high end DAC, preamp stage with superior specs and unused output power potentials don't always result in audible superior sound quality, hence in pure direct mode when operating well within their power limits modern mid range AVR such as the 4000 will all sound great. If I am wrong, I am sure he will correct me. Some of us audiophiles bought prepros and amps for other reasons.
