No link! The test is just as I described it. If you have a turntable with vacuum hold-down and two tonearms, you can conduct the test yourself. It was written up in Audio Magazine many years ago and Micro Seiki used this test to demonstrate the advantages of vacuum hold-down. It is the reason I now own a turntable with a vacuum platter.
Best regards,

I couldn't find a Test disc with an unmodulated track....so I used side C of Daniel Lanois Black Dub which has half the side unmodulated.
I played the Copperhead arm on the modulated first track whilst listening to one of the FR66s arms tracking the unmodulated second half of the record.
I listened through my Audeze LC2 headphones powered by the Schiit Lyr head amp so that I could hear even the minutest reflected tones.....
I even left off my normally used centre brass clamp to allow the record the least amount of clamping action....
The result....?
Not a single sound was able to be heard via the cartridge playing the unmodulated track....
I thought the 'legend' of this so-called 'test' sounded 'suss'...as I had never heard of it in 40 years of audio involvement....and surely such a conclusive test would have been used in advertising by all those marketing their turntables with vacuum suction....?
Whilst the 'myth' of this test seems to sound quite plausible.....it's just another example of the often unscientific and bogus propagation of untruths which burden this industry.
> I couldn't find a Test disc with an unmodulated track.
That's no doubt your problem! The test works just fine and vacuum hold-down works, too.
I don't understand this answer, John. He had a disk with a blank groove, a modulated groove and two arms, meeting the terms of the test. It seems that there are other routes to a well damped disk player.I would suppose that a peripheral weight, center weight and acrylic platter would work as well as a SOTA vacuum, though I really don't know. I only have one arm.

No...I think it's your problem.
Not only have YOU not performed this test.....you can point to no scientifically validated description of this test.
Stating that the test 'works' over and over may give you some comfort......
Truth appears to hold little value in your cosy universe....?
