If you have experienced the effect of STATMat, Finyl solution, green spot light.....then, you won't be surprised by the audible
difference of original CD & its digital CDR copy.

If the digital output from a CD Drive is as simple as the "0" & "1", then there shouldn't be difference of the sound come out from
a Discman (with digital out ) & the ultra-expensive state-of-the-art CD drive. In the early day of release of CD, some scientific
prediction is no need for expensive CD front end for play back of CD disc.

In real experience, many of the HKAVers here did hear difference of sound come out when a tweak is done on a CD drive, included : 
AC power cord, spike, HiFi rack, STATMat, Finyl solution, Elbony laser lens ring, & Shum-mook........, no need for "golden ears" to
experience the difference.

Hearing is believing.
I'm not ignoring science, but wait for scientific explanation of these instead of denying the phenomenon.
