I auditioned an Esoteric G0s clock with my X-01 on my system for about a week and a half. When I unhooked the clock - I could not hear or sense any difference. If there was one, it certainly would not be worth the investment in the G0s. I would guess that with a multiple box player, the G0s would be worth a listen, but with a single box player like the X-01, I just couldn't hear any.
