If this can be done,
absolutely not the AVM90 unless it is for the purposes of enjoying a good lynching here if it measures badly. The higher up in the price pedestal they are, louder the lynch party.
AVM90 at US$7000 is an over-priced box for the life-style crowd with more money than sense. Its performance would be irrelevant to anyone outside its niche audience. It also wouldn't say anything about the more competitively priced AVM70.
It would be a lot more useful and practical to the audience if the AVM70 can be measured instead to see if it passes or not.
Leave the AVM90 for the Stereophile and Audioholics shill crowd.
