conclusion: in short, best solid-state amp i have ever tried!
what c-j 350 is NOT:
romantic, delicate, intimate, light shining from within (a la tube), midrange bloom is missing, highs are not so magical as my ARC, not magically emotive (as my ARC)...it does not do female vocals (e.g Le Mon & Janice) as well as my ARC, neither does it convey the intimacy of small-scale works, or music that does not require power.
conclusion: these are indeed minor grouses against the overwhelming list of positive attributes!
next trial - PASS LAB XA100 mono block and BLADELIUS GRENDEL
