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, Boa, I like pull ups better.I thought its peeing
contest, not pissing contest.I can also insert foley
if you guys need it, with bag connected.IMO
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?
Mr S. smilin, you have to inflat the balloon to keep it secure. Maybe it needs a mod from apl or modwright.

I think I am gettiing the apl so i can compare with the modwright and audio logic DAC.
I briefly compared the Exemplar 3910 and a stock one. I was shocked at the greater quiet and dynamics of the moded unit.
