I've said this before. I find the modern ARC quite different sounding, and for me in a good way. The sterility of before is gone and they sound warm but not yet euphonic, while keeping the sound stage and openness.
Regardless of their ownership, I would use that as my guide. If you really loved the ARC of the 1980's - 2000 then I don't think you'll be a fan of the current line, and vice versa.
I've not done an exhaustive listening, so I could certainly be wrong, or oversimplifying, however if I were go look for tube gear this is how I would organize my search more or less.
Best,
E
