I compared the 17LS to my new CT6. The 17LS was definitely more distant sounding, and not in the same league sonically to the CT6, which was much better. I can't speak to the 17LS MkII, which some here claim is superior to the original 17LS.
Read my review on the CT6. It does not have a recessed sound at all, yet it has a deep soundstage, deeper than any of other preamps I tried or owned. One of CJ's biggest strengths is how it recreates a 3-D image of each instrument, where you can hear the air and space around each instrument. This paints a wide and deep soundstage that separates images in a clearly-defined and natural way that sounds correct and easy-going. This results in a much less electronic, constricted, flattened presentation of other preamps.
The CT6 is not dark or lacking sparkle. There is detail, but not achieved by overetching or brightness. The midrange has some weight and body, which is a hallmark of the CJ sound. I find this combination closer to reality than other brands, and is bringing me much musical enjoyment.
