If you have some money to blow, just get one of these: https://www.gcaudio.com/cgi-bin/store/showProduct.cgi?id=636 From http://www.gcaudio.com/resources/howtos/cartbasics.html Azimuth: Even more critical (in my opinion) to proper set-up than VTA, is cartridge azimuth. Unfortunately VTA gets all the press, therefore many people are not aware of the importance of this adjustment. What is azimuth? Looking at the cartridge body from the front, it is the left to right tilt of the cartridge body. Contrary to popular belief, azimuth is not necessarily correct with the sides of the cartridge body are perpendicular to the record surface. What we're actually looking for is the correct relationship of the stylus to the groove. Unfortunately, the vast majority of styli are not mounted perpendicular to the bottom of the cartridge body, thus making azimuth set-up by sight alone erroneous. And with the current trend toward decreasing stylus size, even seeing the stylus without the aid of magnification borders on the improbable. The "eyeball" or "mirror" method should only be employed if other more sophisticated methods are unavailable. I set the azimuth on my cartridge with a PC and a QA400. You don't need a QA400. A soundcard with free RTA/FFT software will do. You can use jDFT: https://people.kth.se/~johk/jdft/ or other free software. A test LP with separate 1kHz left and right tones is also required: http://www.musicdirect.com/p-8523-ultimate-analog-test-lp-analogue-productinos-test-vinyl-lp.aspx The procedure is to set the azimuth so that crosstalk (bleed from one channel to the other) for each channel is the same. That is, for the reference level left channel 1kHz tone , the right channel output should be the same as the left channel output for the right channel 1kHz reference level tone. Crosstalk is going to be pretty bad on turntables, on the order of 25-35db, so this will be easy see in a spectrum analyzer. Here is the crosstalk (RED) on the the right channel, bled in from the left channel 1kHz reference level tone. Here is the crosstalk (YELLOW) on the the left channel, bled in from the right channel 1kHz reference level tone. Above is a phono of the cartridge with the VPI azimuth alignment rod after alignment using the above method. Note that the stylus is not quite mounted perpendicular to the bottom of the cartridge body! I had previously "eyeballed" it with the VPI rod, and it turned out after measurement that the left and right crosstalk signals were off about 4-5db! Supposedly, azimuth alignment is more crucial to the cartridges with the Micro Line, Micro Ridge, Shibata, SAS type contact tips because the needle goes deeper into the grooves. I can't attest to this, but I can say that after an afternoon of experimentation, setting azimuth using this method yielded a much more stable center image and a more focused precise sound.
