I dont know what the price of the Esoteric K01, but from what ive read, it seems the price in Hong Kong is around the 15.000 USD ?
If so i think there are more interesting players at this or under that price. In no particular order, i would look at the offerings from Linn, Meitner, Playback Designs, Dcs, Reimyo, Accuphase,
Ive always stayed away from Esoteric because they have a tendency to cut a lot of corners in their components, and the sound is too 'plain' (but thats entirely subjective of course).
Would love to read your impressions of the C3800 though, that looks like an amazing machine.
Cheers
