Almost all competent isolation devices and systems use springs in some form or another so the only reason I can think of why someone would disparage cryogenically treated springs is out of desperation and/or ignorance of physics and strength of materials.
Geoff, you misunderstood my statement (again). I was attempting to make a point where a spring that is cryo’d provides an increase in performance but will not hold a candle in sonic when compared to a product costing in the thousands of dollars. And just so you are aware, we have a lot of experience using cryogenics as well.
We notice you use of the word “desperation or as an act of desperation” is stated often when put on the defense but I’m guessing we’ll call this one a simple misunderstanding.
