Ok, imaging. With my Esoteric X-03 SE, I found that vocals sort of tilted to a bit to my left. That was corrected when my dealer lent me an Esoteric G03-X word clock. Images were stabilised and vocals were airier. So it's true, jitter (which is measured in picoseconds) is audible. With my Meridian 808.3, I had the same results - stable imaging and vocals had more air to it - without the need of a clock. I find that the 808.3 is superior to the X-03 SE + clock combo in terms of sheer transparency and retrieval of very low-level detail buried deep in the recording. Delicious!
