In Reply to: RE: If my ART9 sounded like that... posted by John Elison on February 27, 2017 at 09:58:58
Doh! I had forgotten the whole exercise was to check for resonance frequencies BELOW 10 Hz.
I any case, I'm not sure I'm motivated enough to pursue additional test LPs and software to check my tonearm/ART9 combination. It seems to be working just fine with sealed subwoofers. But I may do a bit of research on free-ware or share-ware for frequency analysis and perhaps purchase a test LP with the necessary test tones if I can pick one up cheap.
Thanks!
Tom

Why did you buy the Ultimate Analogue Test LP and how do you use it? In other words, what does it do for you?
Thanks,

I use Tracks 1, 2, & 3 on side 1 with a Fozgometer for azimuth adjustment. I also use Track 3 on side 2 for cartridge "tune-ups", although I can't say that I've noticed much difference before and after.
I don't bother with anti-skate test tracks. I've found that I can do that by just watching the cantilever as it traces the groove and by listening. One of the reasons I like higher compliance cartridges is that you can see the effect of anti-skate on the cantilever suspension. That, and the slight irregularities in cantilever suspension and alignment are overridden by the forces exerted on the stylus/cantilever as it traces the groove. Basically dynamic alignment; you can see how the stylus and cantilever align to the groove as you play a record. At least that's my working hypothesis. '-)
There are other test tracks that seem interesting but I just haven't taken the time to research what I might need to effectively use them.
Regards,
Tom
