'Best' CDP for under $1000 ? Upgrade to GCD-575


Hello
I've got a CJ SD22, and a Adcom GCD575, and am thinking about what I would get/hear for under $1000. There is a CA 840c local, for 800 (maybe) and I see a Mccormack UDP-1 also for about that $.
However, there are a LOT of brands out there, some I've never heard of.
I don't think I'd mind the 'black'/no noise of the 840c I read about...and I prefer the cdp to not color the music. I listen to a lot of stuff but prefer clarity above all.
TIA

Well, FYI, I bought an Nakamichi OMS7 and, WOW. What a diff...got them A/B'd on a 'low-end' Onkyo TX-890...I can't imagine how much better a CA 840c might sound...
Was the Nak OMS7 CDP a design of the 1 & only Nelson Pass as well? I believe Nakamichi used his designs for the PA7 & PA5 amplifiers. Maybe that is why it sounds so good even to this day?
