The bang-for-the buck return in sound quality from such tweaks is so disproportionately large as to create an addict. Just following Uncle Stu's advice of wrapping the amplifier selector and volume pot stems with Teflon tape only takes a couple of minutes but is instantly rewarded. His huge contribution to tweaks is without parallel.
Enclosing the amplifier's internal Toroidal transformer with three or four layers of UltraPerm 80 (hydrogen-annealed MuMetal) each separated by narrow strips of 1/16" thick cork to double their overall effectiveness prevents the loss of approx. 20%-25% amplification due to the fringing effect that would otherwise cause that part of its magnetic field to spill over and saturate/ degrade the performance of the circuit boards, and interconnect input/ speaker output units.
My interest in McMaster-Carr's 85% wool-felt arose from the 'Diffractionbegone' tweeter-surrounds of Jim Goulding and the discovery that, for those unable/ unwilling to afford the footers promoted by Winston Graham/ their equivalents or the final Oyaide Carbon Fiber Wall Plate solution to AC wall unit vibration long advocated by Duster that this felt had a low-cost role to play that was in many, but not all, cases superior to that of cork in other areas too. I use it under many of my components (brass footers have always created a bright sound to my ear and hard composites not much different). Given resources, I would unquestionably use Marigo Audio's footers - Ron Hedrich has the best ears in the business as I have long discovered with the treatment of micro-vibration and static-electricity during play using his Ultima Signature Mat for CD/DVD and ripping, his VTS Tuning Dots (white on tweeter surrounds/computer chips and green on mid-range and woofer membranes/ capacitors); and 40mm Black SuperDots on the backs of speaker cabinets or on French windows at first reflection points for removing the vibration while leaving the view. Time after time after time Ron permanently eliminates the problem with great precision.
