We used our regular Naim CDS3/555PS reference CD player but, as it retails for the thick end of £10000, we also used a Marantz CD6002 - at £270 it's a bit more appropriate.
It's been a little while since we've used a C352 in anger - we'll be testing the C355BEE that's replaced it as soon as possible - but personally I've got fond memories of the NAD's grip, grunt and powers of resolution. Bass articulation is about the only thing we found to criticise in the Marantz's performance, but the slight lack of eloquence is more than compensated for by its overall verve.
I reckon the C352 is a better bet for out-and-out rooming-filling, but they're both expressive amplifiers - a lot will depend on the prices you've been quoted for the Marantz and the NAD. If the difference is the £100 our Buying Guide quotes, there's very little in it on a pound-for-pound basis. And it's safe to say that both are considerably more capable than your speakers are - they have to be your next upgrade.
