My CJ Premier 16LS2 doesn't sound overly warm at all. When I first got this preamp my reaction was "it is not warm enough!" Everyone described CJ to be overly warm, but not in my system and to my ears. It's just slightly warmer but much smoother than SS McCormack preamp it replaced. I understand the older vintage of CJ gears are much warmer sounding. As far as detail, it has 95% of detail compared to Unidisk driving power amps directly playing SACD. I don't miss any detail missing in normal listening.
Conrad Johnson vs Audio Research vs BAT vs Cary
Just recently acquired a mint condition Threshold T400 and love its sound. It will soon be time to upgrade my preamp which is currently a Quicksilver Linestage 1. I'm considering within the $2500-$3500 the following - Conrad Johnson Premier LS17, Audio Research LS17, BAT VK-3iX, BAT VK31SE, and Cary SLP98. I know there is a bit of range here, but am interested to see who has done some direct comparisons, and who is pairing with similar solid state amps. Thanks.
