The stepped attenuator made adjusting the volume difficult. On my low powered SET its great, an advantage actually.
Are you referring to the volume pot in the T7, or the one in the BAT?
If it's the T7, you can set those Noble pots in between notches...
? The T7.. Teh BAT has a digital volume control.
Based on my reading of their white papers, it's still a stepped attenuator, albeit setup as a shunt...
I think the Noble's are not stepped attenuators, but I could be wrong.
