APL 3910, Exemplar 3910, MF KW, Esoteric X-01?


I currently have Krell KPS-28c cd player ($8500). I am thinking about upgrading in the near future. Please help me decide which player – most important for me is “red book” format. The rest of my gears are Krell KCT pre-amp ($9000), Krell 400cx amp ($10500) and Wilson Audio Sophia ($11500). Following are possible players in random order:
Musical Fidelity KW SACD - $7,000.00
Krell CD/SACD – to be released soon (because of CAST) - $?
ESOTERIC X-01 SACD/CD - $13,00.00
APL 3910 - $5000.00
Exemplar 3910- $4000.00

Will I be down grading instead of upgrading with any of the above player?

Thanks in advance for your input

Tvad, I certainly have limited experience with being able to compare the many moded units with few exceptions. It irks me, however, when others make blanket statements that all you need is to buy x unit even though I know few are taken in my such efforts. I warned early on in the shootout that it would end up as a pissing contest as you call it. It, of course, did.

I do not wish to participate in such a contest, but I would urge all to consider the idea of adding IMHO to their comments.
Excellent idea, Tbg. Even if only a formality, the use of IMHO is a useful reminder that these are all only opinions.

Tvad, ever since I started having dreams about audio, I've had to use a plastic sheet on the bed, so don't be too self-conscious about your diapers.

What about the new Parts Connexion Ultimate Tube Stage Mod for the denon 3910?I was hoping some of you may have heard it.I am told they use higher quality parts than APL.I do not know if this is true or not.I was just hoping to get some feedback on this particular mod.
Cheers
