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).
