The HE-6SEv2 are indeed superb. But alas, in the EU there doesn't appear to be an "Adorama version". They cost €1800. At this price there are a number of worthy contenders.Well. Amir has reviewed both (well the He6 SE v1, not the V2 Adorama) so read both reviews .I think he would overall rate the HE6 higher but guess would say the Arya spatial properties post EQ are better.
Sidegrade more than upgrade I would have thought.
(And they may require a new amp: they are hard to drive properly)
