Long ago I had Auricle 70 musicblocs (about half the 160’s in price & power), and have been curious about 160s at times. Almost went for a set a few years ago, but ended up buying new pair of 200iQ’s lol. From what I understand (a friend asked VAC for their opinion) they’re a lot better than the Auricle 70s (which I would hope so - the 70s were OK) but a long ways from 200iQs. Probably a ways away from even a single 200iQ. With nice looking single 200iQs down to what, $7K used, I think it would necessarily need to be under 4K to represent good value. But I’m just speculating. If I were on that kind of budget in the market for an amp, I’d definitely give them a look.
One more data point: I loaned that friend my 200iQs, he had a Phi 200 at the time, and reported that a single 200iQ substantially bettered it, and that two 200iQs substantially bettered THAT (I've heard the improvement from 2 in my own system). Unfortunately for our wallets, VAC amps get better and pricier as time goes on.
