I have just recently paired a new Hegel H20 with B&W 702 Signatures (Transparent cabling), so exactly at this price point ($7,500). I have been thrilled.
Also heard the H390 integrated amp (same price as the H20, $6k) and the H20 sounds far more authoritative, as it should as a dedicated amplifier. Loving the pairing with the 702 Sigs. Feel like the supple grip of the Hegel is really well-suited to give the B&Ws plenty of drive but with firm control.
