To genralize, AR is neutral and SS like, with tube bloom, CJ is a warmer, more traditional tube sound. This is a generalization, but proabably true of the vitages that can be purchased for the price points you are looking at.
What pre amp to use in my system?
I have a B&W CDM 9NT and a Rotel 1080 power amp. I am looking for a preamp. I tried a Adcom GFP-710, it is quite good, alot of dynamics, tight bass, but I feel it is a bit too bright and got fatigue sometimes. I like to listen to female vocal, violin, cello, soft jazz. I am looking for a preamp that will produce smooth, warm sound with good dynamics and sound stage. I don't need alot of bass that I don't listen to rock. My budget is less $400. What would you recommend? I am open to both tube and SS. There is a local guy who build and sell tube preamp. If you were me, will you buy home built tube preamp?
