does anyone sharpie thier CD's???

since there is no explanation for this, only theories... this has changed how i view the digital domain.... first there is a gain of data from the coloring???? if we assume this, then there is generational loss in the CD formatt... (previously unheard of) also why not precolor a CDR prior to recording, (better transfer) also DVD's may improve, etc..... i had the chance with a CD and new pressing of a record, to do a comparison... CD first, vinyl next, colored CD, and vinyl.... i am thinking that there has always been all of the music on the CD..... in other words, the colored CD sounded as solid as the vinyl.. i have all Musical Fidelity KW system. B&W 802 spkrs...... ????

anyone from a manufacturer (or lab) from technicolor, to crest, to deluxe, to sony, to cinram, have all said there is no effect of any kind...this also includes the rings that were sold to the public.

The two pianos may not sound the same, but an "audio spectrum analyzer" should reveal their personal characteristics (harmonic fundamentals, tone, amplitude, etc) as to why they sound different (analogue audio).

As Shadorne explained, and other than the possibility of minimizing correction errors, how can the digital bit stream be modified by mearly painting the CD edge or backside?

Mark the edges of the Steinway with a Sharpie and see if it makes a difference.. :-)
