Thanks for the tip!
Sound isolation tip from a dance club DJ installer
I stopped in my local Guitar Center yesterday (where I bought my Technics SL1210 M5G a year ago) to see if they carried the ART Pro Audio SLA-2 amplifier. I soon struck up a conversation with their sound equipment/dance club gear guru and we started talking about the totally inadequate feet on the Technics SL12x0 series and ways around them.
He mentioned that what he did on a permanent (as opposed to mobile) dance club installation where he was getting too much feedback was to get a couple of gel-based keyboard wrist rests from his local OfficeMax, took the feet off the turntable and set the turntable base on the gel wrist rests, which were like plinth-wide footers. In his case he also stuffed fiberglass insulation under the bass in between the gel pads to kill standing waves under the TT base, but he said it fixed his feedback problem.
As most of you know, I have an SL1210 M5G with PartsExpress/Dayton threaded brass speaker cones onto a cutting board. Until about an hour ago I had Vibrapods under the cutting board, but now I have a couple of gel wrist rests instead.
Before I made it a permanent change, I put a record on, set the stylus on the record, and tapped the shelf that the turntable is on to see how much "thump" came through the speakers. Then I swapped in the gel pads for the Vibrapods and tapped again. Definitely lowered the "thump" by somewhere between 2 and 3 dB, which is about what Isonoe measured (with the sorbothane boots) for their $175 footers.
Definitely a little cleaner, clearer, etc. Tweaks are cumulative and I got my money's worth with these.
