Biketony, check me on the internal circuit breaker feature on the Ref 160M (S). If ARC added that feature, that's another maintenance headache that is eliminated and another "buy" point in favor of the 160M (S).
In the old days, if a power tune blew (i.e., arc'd) in an older ARC amp, it would often take a bias resister with it which acted as a fuse. I hope I don't jinx myself here, but so far the KT-150s have never arc'd. I had the problem with 6550 winged Cs and KT-120s.
Good luck on whatever you decide.
