Damping Plates

There have been many ideas down through the ages for using things on tops of speaker cabinets and electronic equipment - e.g., the now defunct Tekna Sonic dampers, Totem Beaks, Super DH Cones, Brilliant Pebbles, Golden Sound’s Acoustic Discs, and stacking 4” ceramic plates on Small DH Cones. Not so obviously perhaps a spring-based isolation system under speakers and components kills two birds 🐦 🐦 with one stone - damping internal resonances and isolating from mechanical vibration - acoustic and structureborne.

@lowrider57 Not so much touching but close to it. I know that removing the metal cover from my tube phone preamp improves the sound enough to have me leave it off.

Correct geoffkait and absolutely none of it did anything for anybody. The audio fad of the day. It is a shame that legitimate manufacturers do not rail against this stuff. They don't because they have to remain politically correct to sell equipment. The mythology is allowed to continue because it sells equipment. Sounds like politics to me. 

Huh? Are you out of mind? Manufacturers have always (rpt always) been two paradigm shifts behind the power curve. Advanced audiophiles have always (rpt always) been the pioneers of this hobby. Manufacturers never got the memo for power cords, fuses, isolation or wire directionality. They’re too hyper focused on circuits. 👀 And perhaps too busy admiring their own handiwork to pay attention to what’s going on. This is the sort of debate that easily distinguishes the mid fi fanatics from the high end. A myth is as good as a mile.

@noromance  I believe much of the benefit of removing the cover is thought to be the prevention of resonance within. May be off on this.
