Wow... thank you for all of your answers and especially thank you audioengr!!!

Sitting here listening to U2 streaming through the Quad VA-One and reading a thread where OP asks if there is any way to have quiet vinyl and thinking YES,it's called digital!!!

Some evidence that digital still doesn’t retrieve all the information that’s in the “grooves.” Not by a long shot. You’ve come a long way, Baby! But you have a long way to go! 🤠

A. Demagnetizing interconnects, CDs and power cords, e.g., Walker Talisman.

B. Ionizing CDs, interconnects and power cords or Anti Static spray.

C. Applying CD treatments, I.e. Auric Illuminator, Liquid Resolution (RIP), whatever.

D. CD edge beveler/angle cutter.

E. Green Pen for outer edge of CD, Black Pen for inner edge.

F. Silver Rainbow Foil.

G. CD mats such as Marigo.

H. Getting the CD absolutely level during play (as opposed to level of top of chassis).

I. Using a green or turquoise tray instead of black.

J. Isolating the CD player.

K. Freezing or cryoing CDs.

L. Freezing or cryoing the CD player.

I can only agree with freediver. Geoff, you are not providing evidence, just voodoo.
