Isolation stands: snakeoil?

willemj, unfortunately my basic CD player won't read my LP grooves.

Proper setup trumps all, and has the most potential.

you said in your opening post.

most turntables, especially decent ones, have vibration control measures built into them via footers and various construction techniques.

This shows to me, that you understand that manufacturers consider vibration control important.
  
but then you say in your next post.  

I have not bothered to perfectly level the rack’s feet so there is some play / wobble if disturbed.

Well, one can wonder if this is due to laziness ? Who knows, but it is wrong for basic 101 turntable set up, and no one questioned it. The TT platform/stand, whatever type/s - plural - as some use multiple products, under the TT, is/are but an extension of the turntable. Adding an isolation platform/s *whatever cost' under it may get better results, but it is a band aid, if the basics are not in order to begin with.

The big Basis TT has proper isolation built in but it’s $100K. The Rockport TT if it’s still made has a dedicated isolation system built in but it’s $80K. All the rest of them, the squishy feet, the springy feet, are Masquerading as built-in isolation as their spring rates are too high to do anything. The resonant frequencies of the platter, the tonearm and the cartridge are quite low, so it’s the very low frequency vibration that’s the real problem.

I deleted my earlier post because it was too snarky. But I applaud the patience of the other posters on this thread.

@chakster Your remark is not "silly", despite clearthink's opinion to the contrary. Go on and continue your posts.

clearthink has unmitigated gall.

First he states the impossible.

Then he is presented with a genuine and no obligation challenge to demonstrate the impossible.

Then he tentatively accepts challenge.

Then he attempts to dictate the terms of the challenge.

Then he is asked to act privately, and with the inclusion of legal council.

Then he refuses.

Then he cry's fraud.

Then he repeats himself.
