This ad from 1981 was in my pile. The tonearm has brains. I think the graphs are saying one arm is musical, blurry, affected by footfalls and warp-wow while the JVC is neutral. For low frequencies, its design seems to tradeoff the big unwanted shake all tonearms have but theirs spreads and dilutes it across the lower frequencies where the energy is far weaker and has less affect. Smart thinking, I think?! I’ve seen it work and believe it especially when playing high volume music. Of course they don’t say what brand the other arm is. Could be a Crosley disco box? How high was the volume? Could a Crosley do that good?
I just bought a well-regarded Pioneer PL-530, took off the mat, then did a penny drop test on the exposed platter. It was an old test we used to do. It sang like leaded crystal! Might sound more like a small bell. The ringing is so pure and so long. I should record it. To be fair, most direct-drive turntables rang so they had thick mats but the Pioneer’s were always the best. The Pioneer has a thin mat so the question is, at higher volumes would extraneous speaker sounds migrate through the turntable to the cartridge changing the music? It’s very possible and I do remember the Pioneer sweet music going weedy and wild at high volumes. Dr. Jekyll became Mr. Hyde. But then neutral is out and musical turntables are in vogue so that leaves us out of the party.
It was actually fun to put six pennies on the Pioneer platter and keep thumping until the pennies starting ringing. Yesterday, my son had a great time. OTOH, my terrible Y7 also got the penny tests. The heavy platter plus the zinc clamp did its job- it was dull sounding- perhaps better then a belt-drive! Then put its thick super-mat on the platter and it rings like a mouse pad. For once it wasn’t hype; JVC really did have a war on resonances. I guess it is the Japanese purity philosophy. My son didn’t have fun with the JVC and I appreciated that. The Pioneer is much more fun!
Terrible, just terrible, I say! Leave those JVC’s alone! They are a little company, no money or engineers, on a little island with lots of earthquakes. What would they know about things shaking? They don’t know better. They invented Shibata tips, 4-channel, VCRs, and the VHS video format. So what, anyone can be a Pioneer
(notice that little ribbing?), no big deal. No, we wouldn’t want their stuff. They are hungry and annoying mice.
