I have been using a Sota since 1981 and have had it on everything you can think of playing through ESLs. I have not found anything to be as important as using a dust cover during play attenuating airborne vibration by as much as 20 dB (not sure how accurate the meter was). Like protective earmuffs for your cartridge. And, everyone thinks this is poison (except Mark Dohmann). I guess like guitar amps everyone likes listening to distortion? With subtle differences I guess people prefer sticking with mythology than really listening? Boggles the mind.@mijostyn I had a dust cover for my Sota as well. When I added the custom stand and platform the improvement was instantly audible- it was not subtle, and it was also measurable- the latter being done by playing a test tone and cranking up the volume- you could easily see on the oscilloscope how much less 'disturbed' the waveform was prior to the volume control (we had the 'scope on the tape outputs).
We had a modified Empire 208 (which was the platform for what later became our model 208; at the time the 'mods' where a damped platter and an SME5 mounted to it). As you turned up the volume the Empire 'fell apart' sonically compared to the Sota. But when either one was placed on the stand with platform neither one fell apart- at that point the Empire sounded better since it was so much more speed stable (the early Cosmos machines had a stability problem that was later fixed) and had a more massive platter that had more damping. Both machines used the same platter pad as I mentioned earlier and both used the same arm and cartridge.
It was thus very easy to show that the anti-vibration measures were having a profound effect on the system when the volume was cranked up.
