What is more accurate , the fozgometer or the diplay of the oscilloscoop

Correct azimuth adjustment (via Foz) give jaw dropping results as to the mirror (or similar) method.  Rock stable imaging, wide soundstage, etc.

" @mb1audio02 -- unfortunately you’re plain wrong when it comes to measuring azimuth using a test tone and whatever instruments you choose. As Joel notes in the piece I linked to crosstalk is not consistent with frequency and unless you have the time and patience to measure at multiple frequencies setting by ear will give the best results"

You may want to actually ready my posts first before telling me what I said in them. I have no idea what method you are referring to. But I can tell you that Brooks Berdan showed me this method years ago, and that's good enough for me. No offense to Victor, but I'll call him if I need help building an amp.  

Don't bother trying to bait me into a senseless argument on this. I'm not responding to it. And yes, I understand the first thing you'll say is that if I don't respond, I'm wrong and that I'll lose credibility in the AG community. Believe me when I tell you I'm perfectly OK with that.

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.

Benjie, When you say you were "way off" doing it by ear, what do you mean?  Do you mean that the azimuth setting that sounded best to you was way off electrically, as determined by Feickert or Foz? Or do you mean that when you adjusted by Feickert or Foz, you got a better SOUNDING result than when you tried to do it by ear alone?  After all, your subjective impression is what counts, at least in my opinion.
