Using the Chesky disk, I was able to verify no difference in bass output whether processing digitally or analog.
When playing the test section (cut 33) I was able to detect definite voids in the out of phase tests, vs. impact from the bass guitar as each note was strummed when 'in phase'. I could feel the 'impact' in my gut. I have not checked it with the RS meter as of yet, but it obvious when listening.
