I have a Technics SL1210 turntable. Out-of-the-box the turntable has an upper midrange glare, variously attributed to the servo frequency, platter ring, motor noise coming up the spindle, etc. etc. It's none of the above, but rather the resonant ringing of the tonearm tube, which has no foam or physical damping matter inside.
I wrapped mine in Teflon pipe thread tape and it cured it. You can get a roll for about $1.00, which will wrap a lifetime of tonearms. On mine I even wrapped the knurled twist collar that attaches the headshell.
This *really* cleaned up and smoothed out the sound, and the midrange glare disappeared.
Any hollow tonearm without foam stuffing should benefit from this.
