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

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
I have another question.I see a number of comments regarding modded denon3910s .Has anyone actually done a/b comparisons of the stock denon 3910 to the modded versions?Were the differences dramatic or subtle in your opinion?
