I have only listened to Audio Research equipment in showrooms and for a short periods of time but it just never pulled me into the music emotionally. So my vote is for CJ as it has always been my cup of tea just much more musical than any of the AR equipment that I heard. To me CJ is what vacum tube pre-amps and amps for that matter are all about. Obviously at this price point you need to listen to both if you can or if as you state you like the AR sound then maybe your decision is made.
