Esoteric K-01

I'm on the same boat. I did not hear the improvement from adding a clock to my Puccini integrated player, and yet I can clearly hear its effect on dCS separates.

Hi Elberot2
That is very interesting! Thank you for your input. I would like to hear from others with external master clock experience.

Keeping to the topic: I utilized a G-0s in Rb-oscillator mode at 176.5 clocking rate with my UX-1 Limited; I did find a perceivable improvement in the sound. It was more subtle in some ways but was there and was noticeable when the clock was removed. I also agree with a prior poster that for synchronous digital playback a hyper-accurate clock (ppb rating, not ppm) does provide benefit. With single box players as I mentioned above, the improvements are more subtle, however, with multi-box stacks (like the P-03U/D-03 combo), the improvements are very noticeable, obvious and missed when the clock is removed.

This is very interesting because the UX-1 Limited converts DSD to 88.2

Did you hear this improvement with CD or SACD, or maybe 176.4 DVD-A?

Agreed!

If there is an improvement in sound of high-end single box players (like the Esoteric K-01) when used with a high end external clock like the GORb it is very minimal and subtle. In fact the difference with and without the GORb clock is so incredibly minor that it is extremely difficult if not impossible to detect even with very careful, extensive A-B comparison. Personally, I don't think the GORb has any detectable sonic affect on the K-01.

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

Is there anyone out there who can compare a high quality single box player (like the K01) with and without a GORb in a blind A-B test and consistently, coreectly indicate when the GORb is on and off? I think not, even you, Alex.

I challenge anyone to prove me wrong. This applies to high end single box players only, not multi box players (where high quality clock use should be easily detected).
