@emaillists, adding the AD Emperor Clock to the EtherRegen, in my system, added greater subtle detail (microdynamics) to the music such that imaging, sound stage and the emotional impact of the music was greatly improved. I listen mostly to acoustic Jazz Trios and guitar. At half volume the illusion is complete and the performers seem to be present.
However, in my case it is difficult to ascribe these benefits to one componet/tweak only. I added the ER, the Clock, a TWL ethernet cable, a Silnote BNC cable, an After Dark LPS for the ER & Clock, a Zafino power cord, two AudioQquest NRG power cords and an Acoustic Zen Krakatoa power cord, as well as an ancillary Supra Cat8 cord from the jack to the ER all around the same time. I can say that SQ improved incrementally with the addition of each component over the course of the two weeks these pieces were added -- the ER first, then the TWL & Supra, then the clock, then LPS, then power cords, then two weeks for all to settle/burn-in. I did not, however, perform a detailed evaluation of each addition separately.
During this process I could definately hear the improvement brought by the Clock and a proper BNC cable (I used a generic BNC cable for a couple of days before getting the Silnote).
