Metrum Acoustics Pavane or ESOTERIC N-05 or ESOTERIC K-05X?

I am owning a system consisting of Amp MCINTOSH MA8000 + speaker Dynaudio S5.4 + CDP MARANTZ SA8005. I used to audition computer audio via built-in Dac in SA8005 and MC8000. Now I would like to enjoy a music of higher quality (both in CD and computer audio), therefore I want to replace my DAC or CDP. I have three options for my choice:

1/ Metrum Acoustics Pavane
2/ Esoteric N-05
3/ Esoteric K-05X

I , as a newbie, do not know which is the best. Please give me an advice.

Any help will be highly appreciated!

Thanks all for reading
