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


Would like to know sure about the azimuth of the cartridge ,a visual check first ,than the result of the fozgo , just a bit differance between the left and right channel , than both channels in mono , green led and a little shiny of the red led for the right side .Than looking at the display of my techtronix dual beam oscilloscoop , both channels 
even , no differance in amplitude . Playing a piece of music , perfect ! What is true ? Can you adjust your cartridge with the fozgo with results in the description ? Ofcourse I did the calibration of the fozgo.

@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

There have been other methods suggested in the past. A particularly popular one was offered byVictor Khomenko in the late 90s and seems to have been widely accepted since. In our experiments, we’ve found that, while this method works very well at a given frequency (most people seem to use a 1 KHz tone for this purpose), it is unfortunately not consistent throughout the frequency range found in music. We discovered that after adjusting the azimuth for perfect balance at 1 KHz with this method, voltage readings with a 100 Hz and a 8 KHz tone give widely different results; one channel would be greatly emphasized at the lower frequency, and the other one at the higher frequency. So while the method is theoretically sound, it fails to address the reality of the musical signal, which is far more complex than a single sine tone. So, until a better and more reliable method is established, our ears will do nicely... and they’re free...
Additional note: to be fair, it has been suggested that crosstalk is not constant on all cartridges. Some cartridges (a few?) demonstrate excellent consistency across their frequency range, while many don’t. For what it’s worth...

ps for measuring timber I’ve found a tape measure works quite well 😏 , measuring timbre requires a depth of musical experience and a good ear, no electronics can help here


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

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.
