I have owned or sold every model that you list. I like the older CJ sound, but like the ARC better. IMHO, the ARC gear is built much better than this vintage of CJ gear. I almost always had trouble with dirty volume and balance pots, bad turn-on relays and noisy switches with the CJ. Never a problem with the ARC.
The CJ sound tends to the warmer, darker, sweeter side of life and the ARC has better bass control and throws a wider and deeper soundstage.
If you decide on the ARC, make sure you get a SP9MKII or MKIII. The SP14 is wonderful. I think the phono stages are superb in either one. Plus, these only require 1, (SP14) or 2,(SP9)of the same tubes. Makes tube rolling easy and inexpensive. The CJs have many more tubes of different kinds to replace.
