Feature Idea - Audio Quality improvement when changing speed

Whenever you retime a clip / change it's speed/duration, and you apply "Maintain Audio Pitch" it goes from sounding natural to sounding like its passing though a metallic filter, and it becomes more dissonant and tinny, or misaligned stereo-wise. You don't have that problem when you do not maintain audio pitch, however, now it is helium sounding. Both are unusable. I've heard you can work around with using Retime with no maintain audio pitch, and then also apply a Pitch Shifter. That is too time consuming when I need to retime 3-400 clips per project. If Adobe is expecting editors to have to load up all their audio into Audition then back into Premiere, that's a horrendously clunky solution.

Is there any way to make it so that Retime along with Maintain Audio Pitch doesn't make clips sound tinny and dissonant? My client hates it and is urging me to use Final Cut because it does not have that problem.

Real professionals use Premiere for their work and income source, this is far too simple of a fix to be a problem for professional software that we pay monthly for.

Thanks!
