Esoteric P-03/D-03 or Esoteric K-03


Of the above mentioned units, which would be a better purchase? If the DACs in the K-03 are considered better than the previous P-03/D-03 models, then is the K-03 a better choice or is the older pair a better choice used? A new K-03 is a few thousand cheaper than the other pair used. Thanks in advance for your advice.

Yeah, the K-1s are currently going used for about the same price as the P-03/D-03 combo used. But all of the ones I've seen on sale are out of my voltage. I'd prefer a 220-240 volt machine if I were to go that direction. The K-03 new where I live is cheaper by about 3-4 thousand than the combo unit used. Thus, my asking of the question. I won't be able to audition the used combo unfortunately, but later I might have a chance to hear the K-03 before purchasing. My sense is that given the recent changes to the Esoteric gear and the trickling down of technology to the single box machines, they might be a better choice overall then the combo, which surprisingly enough might well be overpriced used given these changes. However, that's speculation on my part and it would be good to hear from someone who's actually heard the gear and can compare reasonably well. Your comments are helpful, Jimmy, so thank you for that.
Jimmy, what is your experience with the Dynalab internet radio played through the Esoteric K01 DAC? I am looking for the right way to listen to internet radio through my rig. I would also like to listen without switching on the K01 at times.
OK. Some helpful discussion here on this topic: http://www.head-fi.org/t/533409/new-esoteric-players-k-01-k-03-anyone-has-seen-or-heard/15
