mains - you might possibly be mistaking me for someone else as I never mentioned the Townshend video. I am a strong proponent of isolating everything due to the deleterious effects on the audio signal of seismic vibrations - produced by traffic, wind, ocean tides, speaker feedback, subways, footfall, local construction projects, Earth crust motion, etc. Generally speaking I eschew racks since most of them exacerbate the floor borne seismic vibration although I can certainly appreciate that racks organize one’s components. I also do not favor any vibration isolation device that employs rubber or really any soft materials whether for damping or any other reason. As far as your experience goes, everyone has a story and yours is neither better or worse than another's.
