Ihave had both AR and CJ preamps but not exactly these same models... anyway... I have found that the AR sound is more linear (freq. response) but a tad grainy (midrange) in comparison to the CJs, which are more musical but lacking the ultimate extreme resolution at both ends.
Please consider that I have not had the more expensive models of both companies - which is exactly what you are evaluating.
