Actusreus - use your amps terminals rather than your speakers. With a voltmeter set to AC, the 5V setting should do nicely. Also you will need a test record. Below is a link to an A'gon write-up I did a while back - there is nothing unique about it. I've only seen pictures of the Fozgometer, but using it will involve essentially the same technique as a voltmeter and the latter will be less expensive.
Some cartridges more than others are sensitive to less than optimal azimuth. Unless you have a Graham or Triplanar or other tonearm sporting a good azimuth adjustment interface, then adjustment can be a bit fiddley but once you've done the voltmeter technique a couple times, its pretty easy to iterate across multiple adjustments to fine tune the crosstalk and get things nicely dialed in. Dougolsen gives a good description of the characteristic benefits of proper azimuth. I find it worth the effort to get the readings so I can gauge if adjustment is needed and have the peace of mind in knowing. Good luck with your cartridge setup!
