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

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.
Modwright, Exemplar, APL? I'm thinking of upgrading to the modwright Sony 999es. On a dollar basis you can pick up the Sony for $500 and get the full mod from Dan for $2,100. I'm not interested in DVD-A so the Denon 3900 isn't a requirement (unless it sounds so much better). It's always difficult to compare so I was interested in any feedback on the Sony/Modwright combination. I have some info from the threads but am always looking for more recent comments. Thanks.
Goose, I doubt if any more expensive unit gives twice the quality of sound as they cost more than twice as much.
