Chebby has a point. I like the XS/CD5x, so much so that it's on my shortlist. For once, I agree with every review I read. But ... and it's a big but, if upmost clarity, transparency or whatever you want to call it is top priority for you ... others do it better. Especially the AVI's messiah suggested though you have to compromise in other ways.
I don't know Neat products so can't comment but I used Mordaunt Shorts MS20i's with your system and everyone, including shop owner, was impressed. They have a super clear, very open sound. Although not in the AVI's league of clarity the Naim system nevertheless imaged fine without loosing drive or punch. I believe AndrewEverard once commented they where developed using Naim electronics but I may be wrong.
