Azimuth 2020

Very interesting discussion. BTW there is a new tool on the market, built by Sperling, the German Phono builder: PDM-1 by Sperling Audio. Looks much more serious than the Fozgometer. I have no experience with it.

usually I prefer adjusting Azimuth with well known puristic recorded LPs. I am not looking at the center stage reproduction rather than at an equally room reproduction in both channels and at the straight edge on the sides and rear of the mapped room.

If you know where to listen to it is very simple. With perfect Azimuth alignment it is all about degrees... it is about arc minutes (=1/60 degree) or about arc seconds (=1/3600 degree!!)...

Not sure why I would give a company free consulting. Fosgate device is just one method. Not my fault it does not properly set azimuth for cartridges without perfect manufacturing.
Lewm, I linked an article with graphs that show high frequency response with and without proper azimuth alignment.

"PDM-1 by Sperling Audio" and it's only $2026.   

Looks like the same concept, minimize cross-talk.

I guess I will find out about the two tools, perfectly manufactured and aligned and do report about my findings.
