Solid Air Audio Thingies??? ....These are nothing like them at all...these are machined from Delrin and suspended using NBR o-rings and are designed and made by Peter ( gwernaffield ) They have no association with Peter whatsoever...If you want a proper set of pylons to support your Michell TT...believe me..these are the boys...I'm hard to please, and I don't part with my coppers easily....but these are exceptionally impressive...and worth every single penny....
