Esoteric K-01

"Unless the A-B comparison is performed as a blind test, it is useless; psychology can play tricks on audio perception."

Very good point matjet.... Fact is that, I did perform exactly that "blind" test with G-0Rb clock on K-01 at the Esoteric suite at RMAF... I started from an extremely skeptic position, because of past experience on X-01... But I had to change my mind.... and I seemed to have no problem determining when the clock was on or off.... How was my test "blind"? rather simple actually... I am in fact a blind audiofool and could not see what setting was being activated on the machine. G.

My Esoteric based APL NWO-M has a bunch of the latest AKM DAC chips in it. Although the machine sounded very good new, after about 359 hours, each format sounded significantly better to me.

In addition, there was no difference using my Esoteric G-os rubidium clock with the NWO-M, however when I used the clock with the UX-1 Ltd as transport only with another DAC, the clock DID make things sound noticeably better. I was not in the Esoteric room when the clock was A-B'd with the K-01 at RMAF. I now wish I had been Based upon my limited rubidium clock experience, I would agree with Matjet as to the clock's best use.

If indeed the clock made the K-01 sound better than just the K-01 by itself, as my friend Guido witnessed at RMAF, it totally calls into question the quality of the K-01's internal clock(s), I would think. Not sure how you can really AVOID such a conclusion. Again, I would want to hear the A-B myself, in my own system, before I can draw any conclusions about the K-01.

Guidocorona,
Try the G-orb at home for a few weeks before you buy. Let me know what you think after a few weeks of home testing.

Thanks alot guys for all the value info on breaking in the K-01. Will look into obtaining the esoteric break in disc.

On G0 rb clock benefits, sharing the below clock specs i read about when i was reading about the K-01.

Esoteric D-01/D-03: ±3ppm
Esoteric D-02/K-01/K-03: ±0.5ppm
Esoteric G-03X: ±0.1ppm
Antelope OCX: ±0.02ppm
Antelope Isochrone Trinity: ±0.001ppm
Esoteric G-0Rb: ±0.00005ppm
Antelope Isochrone 10M: ±0.00003ppm

Basis specs, that should explain why adding a more superior clock to the K-01 will hear some improvement.
In reality, one needs to hear for themselves if the improvement justify the cost for the clock.

Cheers

Golden words matjet that I shall heed... I would definitely do some careful at home trials before committing to any clock... or any new CDp, including K-01... A false positive can turn into an, uhrn.... Expensive proposition:)!

Saluti, G.
