The ARC LS-25 MKII vs the CJ 17 MKI, well the ARC was more detailed in the overall presentation and the CJ a little sweeter sounding with less details and dynamics (more tubish). I would have preferred a preamp that combined both of them. The ARC Ref 2 MKII would be the combination IMO. Cannot help you with the others.
Happy Listening
