Moving up to audiophile cdp

I am considering moving from my meridian 568 doing all processing to a separate SS preamp, inexp. processor, and quality cdp OR DAC. Thus far I have only used BB sony cdp/dvd players going into my meridian. I'm interested in the following:
Moon Equinox
Meridian 508.24
Sony scd777es
Music Hall Maverick

Any suggestions are appreciated. Would I be better off still moving away from the processor with a reasonable pre and getting a good dac to use with my existing BBuy cdp?

Thanks
