Yeah, I guess I would expect it's a typo too. After all, we all know the Outlaws know how to do proper analog BM from the ICBM.
I guess it *could* be possible the the 100 Hz low pass only kicks in *if* the 80 Hz switch isn't engaged.
Oh yeah, an anomaly in the review they don't mention, but that's there: the pre/pro doesn't have balanced outputs, yet the amp has balanced inputs. What do you want to bet, when (if?) the big brother to the 950 comes out, it has balanced outs!
