I've listened to a higher-end ($9K-ish) Jadis and it was impressive.
I have Harbeth 30.2XDs paired with 2 REL subs - powered by a Raven Audio Osprey, which is also impressive. Customer service is equally impressive/personal and they offer a 45 day trial if you are in the US. Just started tube rolling - now the real fun starts.
They only sell direct so you can figure the math (Cost/Value)
