Naim CDX or BAT VK 5CD?


I'm shopping for a CD Player and wonder whether any of you have had the honor of auditioning both the Naim and the BAT. If so, where would your preference lie? Also, does anyone know what the SE upgrade costs on the BAT, and whether it would be worth it? Thanks for the expert advice!! John. I'm using Bryston ST amplification and B&W Nautalis 805s (for now :-))

Hifinut you are dead on. I own a cdx and can say that by itself it is a very respectable player. However with the addition of an XPS it transforms to a level that very few players can come close to. I have heard a BAT VK 5 it is a very nice player however I find the CDX more to my liking the CDX/XPS combo is in a different league. Just my two cents and I might add that the CDX is really at its best in the confines of a full Naim system. If I were looking for a player in a mixed system I would want a home demo of the players in the context and synergy of the system in question.
I'm just starting to get on the Naim bandwagon, and awaiting my newly purchased CD2 next week. The rest of my system isn't Naim yet, but from the music I've heard from a my local dealer's all Naim system (CDX/102/Hi/180/SBL), the CD2 might be the beginning of a very long and expensive relationship with Naim! :)
Naim CD players sound great with other folks' gear. Don't lock them into Naim systems unless you already know you like that combination. My CDX/XPS is in a system of Blue Circle electronics and it sings like a damn bird. BAT has a wonderfully rich midrange but can't complete with Naim anywhere else, say my ears anyway.
