The NAD C352 and NAD C542 CDP/amp combo is a fantastic deal via Superfi.co.uk
Along with that i feel you'd be better going for the M/A RS6's over the RS5's
I have the RS6's and theyre superb speakers wand they really suit the NAD combo down to a tee. My mate has the NAD C352 and the NAD C355BEE amps and i auditioned them with his C542 CDP, my Arcam Alpha 9 CDP and his M/A RS8s and they combinations were brilliant.
Not sure on what music you listen too be we tested them with everything from Pink Floyd to Hed Kandi to System of a Down and they all worked really well together.
Superb, well controlled and timed deep bass, smooth midrange and crisp/clear treble.
Found that the speakers were best about 30" from the rear wall and away from side-walls but the bungs also help is space is limited.
Im toying with the idea of replacing my Arcam set-up (apart from the CDP) with the NAD C355BEE and C542 CDP/amp combo.
