Welcome to APUG , Stan.
Our member Bob Crowley is an expert on medical imaging with ultrasound also. He developed tiny sensor for imaging in heart and he says he was very successful. He says all microphone experts came from medical imaging and he developed a nanomaterial for ribbon microphones and Shure invested and using 30 years may be more.
I follow his blogs especially microphonium. I discovered there how much 70s symphonic rock groups depends on the quality of ribbon microphones especially when the microphone made an angle with amp.
Sounds goes harmonics rich and more beatiful.
And I read lens design have a similar trick , Leica caliber the lens to film plane angles and their harmonics and give the famous Leica feel.
I think selling your F3 and switching to Leica will open new gates to see the difference. Sound perfect mixing and visual perfect mixing are the same.
Best ,
