Mike, I have'nt a clue why the X2 was'nt a match, it was a complete mystery to me and the helpful dealer. It produced an audible hum even with the volume at zero. I tried different cables, supports, I even tried with a friends Aleph 5, same hum. Pass Labs could'nt explain either. I am not saying you would have the same problem at all.
As for the CJ 17, no tube wooliness at all, detailed, but not harsh, the expected great tube midrange, but good base too. Also the widest soundstage I've heard with the Aleph 3. I loved that amp for it's detail and sweet tone, but it does'nt throw a very wide stage. I have listened to a number of tube pre's and am a commited CJ fan. IMHO you will find it hard to beat under reference grade pre's, plus they are reliable and the firm give excellent after sale service. If you can. give the combo an audition somewhere, I think you will be impressed. best wishes
