Vintage tube preamps: CJ or ARC?


Leaning towards a tube preamp...any thoughts on the Conrad JOhnson pv-5,10,etc,,,vs Audio research sp-7(?)? Looking for classic tube 3-d sound with decent highs...

2nd the PV5. I still use mine and with my speakers/room and taste in tunes, I figure I would have to spend about 5 times the price for a new full function preamp that would be as enjoyable.
