With my audition of the IRD Purist, I'm finding that the 3-position gain control is a feature of brilliance. Is Curt the only one offering this? Are there any other pre's you are aware of that offer multiple gain settings?
So far, acoustical music sounds real at 0 gain while other types of music seem to improve with more gain... rock, for instance. I can see myself using this feature extensively.
