I don't see how any of that applies here. Not only that, the last 2 sentences are just plain wrong (unless there's a communication issue and I don't understand your statement as you meant it.).
Yes, it would appear that it’s a communication issue. When I first got into turntables, the home hobbyist had two options in setting up his cartridge azimuth. Have an experienced turntable technician set up the table who has over time developed the acute listening skills necessary to be able to discern the subtle difference that azimuth has on performance (similar to my old piano tuner), or develop the listening skills yourself.
Today, the home hobbyist has access to very accurate
DVM, Fozgometer etc., which will allow him to set up his azimuth without
necessarily developing the prerequisite listening skills, just like today’s
piano tuners who primarily rely on the use of electronic devices to tune a piano.
Some tune azimuth by ear and don't give a darn about measuring. Some measure azimuth using an instrument and leave it at that. And others measure azimuth with an instrument and fine tune by ear. Just because someone has a preference for a method over another, doesn't make the other 2 incorrect.
