To LP Listeners: Fozgometer Experiences...

@inagroove 

If you're a bit computer and hardware savvy, you can download REW, buy a decent ADC, and good test LPs and you will have a very good test station. Using REW (and a test LP) allows one to see the channel balance and separation very accurately. You can balance the crosstalk to less than 1dB. Balance is easy to read out. In my decade of doing this, I have never seen channel balance disturbed by changes to azimuth. It is theoretically possible, but in practice, small changes to achieve a sharp minimum in crosstalk has little effect on the broad balance peak.

There are many more characteristics of your system you can measure with this setup, one important one is distortion. 

Test LPs that I've found most effective are: Ortofon "Accuracy in Sound" Record and CBS Laboratories' STR 100. You can find both at Discogs.

Thanks to one and all for the sage advice. 

Much appreciated and well taken (I will save the $ for something else...)

@inagroove Interesting thread, a question I wondered about, but never asked. Thank you. 
 

@kevemaher Thank you for chiming in. I have used an oscilloscope with Analog Productions test record to dial in my azimuth, and I have REW running on a Windows laptop; can you recommend a decent ADC that you reference so that I can ‘up my game’ as it were. I’m intrigued by your test method.
