tosh:I've never really been happy with the Arcam,just sounds lifeless. The Nad gear is supposed to excel in the midrange and this would suit my listening eg vocal,americana etc
Exactly how both I felt about the A65+. Dull, lifeless, and boring.
You'll love the NAD sound. I would look at going up to the C325BEE amp. The C325BEE is a stormer and not that much more expensive. This will give you plenty of current and drive for the KEFs and I bet you'll never want to switch it off. Would be refreshing after the Arcam!
By the way, the Cambridge isn't a bad CD player. Could be worth trying that with the C325BEE first.
