If the CJ DV-2B is the single-box unit, no I haven't heard it. My experience with the tubed dac and transport was so miserable that I wouldn't take one as a gift, which I recognize is an unfair assessment. The $3600 transport/dac combo I had was frequently in the shop (luckily I live within a half hour of the CJ plant), and the transport wouldn't recognize CDRs, CDRWs or about 10% of my CDs. And as I said, it was RESOUNDINGLY outperformed by a Pioneer DVD player. AFTER I got rid of it, my audiobuddies all told me how much they disliked it (thanks, guys). Yes, it did sound warm, laid back ... and really veiled.
I now have an Ack dAck 2.0 with the teflon cap option, playing thrugh a slightly modded Toshiba 3950 and it is an outstanding combo, sounding quite a bit better on Redbook discs than my Sony XA777ES SACD/CD player.
I do confess that I loved the LOOK of the CJ combo, enough to stick with it way too long. As the saying goes, YMMV. Dave
