Esoteric K-01/K-03 Owners

"I have not heard about this in the USA. Can the DAC be upgraded in the K-03. I like my CD collection and have no plans for streaming or downloading music".

The Esoteric Rep indicated they do not plan to upgrade the DAC or provide any additional upgrades offered via the K-01x/K-03x other than the USB input capability extended.

Follow this link (Scroll to bottom of page) and it specifies their intentions at this point. Perhaps they will offer additional K-01/K-03 beyond the USB interface when the time comes, however; the Rep said do not count on it.

Unfortunately, as far as the Esoteric HR Audio Player goes, it is not compatible with my version 2010 Mac Mini (10.6.8) unless I upgrade my OS to Maverick. Fortunately, I am pleased with Amarra 3.0.2 and Audirvana +, though I would certainly be interested in hearing and comparing SQ if I could.

Hi John, is the HR Audio Player able to play redbook material, or only High Resolution files?

Guido

Guido,
Yes, it supports RedBook CD playback as mentioned below:

Supported file formats:
Simple screen design reduces CPU load and contributes to higher sound quality.
By using a simple screen design, the CPU load is reduced, and this contributes to higher sound quality. For listeners that desire even better audio quality, the RAM buffer playback loads the data temporarily into the computer's memory before playback to enable playback with even higher audio quality.

That is fascinating Mark... I wonder if there will be always a sonic advantage in playing redbooks from the K-01X spinner, or there will exist some setup from a PC/Mac such that playback of redbook files from computer will be superior.

Guido,
+1 Mark's comments above. Yes, it would be interesting to compare redbook files via the HRA player to CD's spinning in the transport. I shall evaluate this and revert.

Mark,
The HRA player does not do native dsd for the K-01/03. While I did not download dsd files in the past, I can do so now to evaluate the DoP protocol. Would be interesting to compare dsd over pcm to hirez pcm for some music albums.
