Why does the copy sound better than the original

There are a lot of other tweaks that work as well, such as:

vibration damping mats or stick-on mats

exposure to flourescent light at close range just before playing the disk

Some colored pens on the edges help

This is just getting silly though. Get a Mac Mini and sell the transport.

OK, Nespa light treatment, Intelligent Chip, Audio Deske edge beveler, Cream Electret, Red X Pen, if ya wanna get all esoteric Like. I'm also a big fan of scattered laser light absorbers, cryogenics, CD fluids like Liquid Resolution, demagnetizers, ionizers, black pen for inner edge...you know, anything to give me an edge.

CD is a dinosaur. Get a hard drive.

There was an issue in TAS where Peter McGrath, engineer for Wilson recordings, heard a copy of the CD and it sounded better. I believe the word he uttered was "impossible!"

As it turned out (on CD at least), the CD-R/RW pits are wider than the commercial CD pits, and so the copy is cleaner, and sounds better than the original. Robert Harley also commented on this phenomenon in the pages of TAS 3 or 4 years ago when it was discovered that it was the blank discs that were responsible for the better sound.

That's weird. The pits are narrower on Blu Ray discs and Blu Rays sound better than either CD or CD-R. Wassup with that?
