Dear Kipdent, on the price level we are usually talking about in high-end audio NO customer should accept a cartridge with anything less than a perfect 90° orientated stylus.
On this premise azimuth adjustment in the tonearm is indeed obsolete.
If a customer requests azimuth adjustment to compensate lousy quality control by the manufacturer of a given cartridge, that is another story.
One should however take azimuth adjustment VERY cautious, as ever so often it is NOT a misplaced stylus which is compensated, but differences in output between the two channels.
This is ground full of trap-holes here.
As for Fozgometer and similar products - they do find their buyers and many feel comfortable with them.
Fine.
I for one expect - as a conditio sine qua non in priori - that a cartridge I buy features a dead on 90° stylus.
Would you accept track and rake errors in your new car's axle beam ??
Can't imagine that.
Likewise I see no point to accept a manufacturer misplaced stylus in the first.
