When I said the Creek's isn't a party animal, I mean it lacks the rhythmic drive and attack the very best at this price offer, so if you like hard-charging music (anything from dynamic classical to dance tracks) you may find it lacks a little excitement.
I'm afraid i'm not familiar with the Carver kit, but if it is indeed a smooth, polished listen you'd probably be best pairing it with something with a bit more punch, or your system could end up sounding a tad dreary.
A player that immediately springs to mind is the Exposure 2010s (list price £599), a five-star player with bags of pace and dynamism. Audiolab's 8000CD (list price £600) should also be on your audition list, and (if you can stretch to it) the Roksan Kandy III (£650). And while you're at it, the double Award-winning Cyrus CD6s (£650) is a must-hear, too.
If that's all a bit pricey for you, take a listen to Arcam's evergreen Diva CD73T (list price £450) - an Award winner in 2004 and still a five-star favourite now.
Hope that's given you some inspiration!
