Onemug has good advice. Listen to the equipment not the dealer. I used to go to a local dealer and no matter what I mentioned, if he carried it, it was perfect for what my needs were. If he didn't carry it I got the stories. I used to carry it but too many problems, etc. As far as your concerns here. Q1: I beleive some of the magazines and many owners catagorize McIntosh as audiophile. Q2: there will be a differnt sound both being high quality. The decision will be what your ears like between the two. I have only heard one CJ Pre-Amp and cannot tell you the model. I have owned many McIntosh pre-amps but never tube. You really need to hear the two. One thing I will point out is that it seems that Mcintosh retains it's value better in the used market.
Also the service from McIntosh is impeccable. But that opinion as you may have gleened already is somewhat biased.
Bottom line the CJ dealer was selling CJ that day.
