Thanks for the responses.

Good info there too Barry, very interesting.

Well I've pulled the trigger on the errr.... Proart's.

Couldn't resist after such a ringing endorsement. Hope you weren't all just pulling me leg!!

I'll also definitely look out for an early British 909 as they seem the "perfect" accompaniment to the 63's.

Power and control with a synergy born of design.

Will be trying these out on various speakers also just for fun.
