Test LP's Worth it?

I've owned the HFN&RR test record for about ten years. It hasn't left its sleeve in the last five and I've set up dozens of cartridges on multiple arms without it.

If I connected a cartridge with the channels reversed or out of phase (did that once, lol), I'd surely notice the moment I spin a familiar LP.

I find it useless for anti-skating, which I can adjust more accurately and faster by listening to music.

It does work for fine-tuning azimuth, provided that you have a Fozgometer or a bandpass filter + multimeter/oscilloscope and the time to fuss with them. I've done it. What it taught me is that I can fine tune azimuth as accurately by listening to music, and faster too.

Stringreen's right that you need one to use a Fozgometer. Of course that just brings us to, do you need a Fozgometer? ;-)

Can't justify dropping $299 for a Fozgometer, protractor or a bandpass filter + multimeter/oscilloscope etc. I've used the MoFi disc to set up alignment, overhang, etc.
Just wondering if these LP's were worth it, but at $39-$49 it's not a real big investment after all.

I have a Shure test record and it is invaluable in testing resonance with arm and cartridge. Make sure the test record you get has this test included!

There are some on Ebay for $20. It is called Shure era IV TTR 115.

I have both the HFN Test Record and the Cardas Test Record. IME using the HFN I would not depend on it for anti-skate adjustment. It tends to cause overcompensation for A-S. I found better results using the dead wax tracking method (you can find it by doing a search on AA) and then music to fine tune.
