Know of a "Dirt Cheap" tweak?

Ever experimented with double sided Scotch tape?

With clean hands, try a piece on the underside of a component, so that it is also in contact with the vibration control device.  Or between the original feet, and the shelf.  If you have removed the feet, place the tape
between the shelf and the bottom of the vibration control device.

Try this anywhere two pieces meet where electric current is not
present... supporting components, wall treatments, HFTs,
securing cd mats to cd platters...

I think the tape comes in different widths, and is usually available
at craft stores or online.

I would simply note that Audio Desk System recommends the application of BLACK to the outer edge of CDs. I have done blind listening comparisons with fellow audio enthusiasts utilizing a highly revealing system  (Meridian 808.6, ARC Ref40/250SE, Magnepan20.7) with a clear consensus for black over blue/green.

I’m aware. They’re wrong IMHO. As I recall the CD treatment that’s been around forever - Auric Illuminator I and II - also recommends BLACK. I think they even give you free one. They’re wrong too. Now that you mention it, I’m not a big fan of blind listening tests. They don’t prove anything. Again IMHO. As I already pointed out the CD laser nominal wavelength is invisible at 780 nm. I know what you’re thinking - but BLACK absorbs ALL colors AND infrared light. 😀

Thank you for your opinion.

Exactly the point!
