Opinions on Dynaudio Confidence C4

I have the C4's for 6 months now.
My system: Krell KPS 25sc, Bryston 7BST monoblocks, Transparent Reference cables.
I used to own WATT Puppy 5.1's and before that Sonus Faber Extremas and B&W 801 III's.
I am delighted with the C4's.
Very dynamic, almost full-range (down to 25Hz in my room), extended top, fantastic soudstage.
In my room I have a midbass hump +6dB around 80Hz (used to have it with the Wilsons and B&W's as well.
I would like to hear other opinions regarding the C4, and how they match with other amps and speaker cables (any Nordost users with the C4's?)
