The volume is adjusted by shunting your amp's input to ground via our volume control to ground and allowing the signal to flow into the amp by a "valve like" circuit. The clarity and detail offered by this type of circuit truly blows away all other passive solutions next to a 100% 1% resistor-based control."
It's the old "in the signal path" myth (or not in the signal path) and it's total bullshit and makes me think they don't know the first thing about electronics.
I set out my arguments against this type of attenuator in post #24 in this thread
