looking for best isolation platform for CD player

Error correction is one reason car and portable cd players work so well in poor environment.. I have implemented many ways that make for less error correction and therefore better sound..Tom

The more robust players such as those for jogging feature data buffers, so if there's a momentary loss of data due to shock, it is transparent to the user. So this is not error correction per se but data buffering.

Geoff I have an older Denon player in my collection that also had a data buffer. Adjusting the laser focus offset and focus for the eye pattern, all way before the error correction, improved the sound with each little turn. I have a propretary device I use that will reduce laser scatter and decrease error correction as well as four other benefits..Tom

makes sense; the laser reading process seems critical to final outcome. The off the shelf player does OK but not anywhere near perfect.

Theaudiotweek...Please explain how error correction has any adverse effect on sound. An error CORRECTION code enables recovery of the original data, as if no error had occured. This is true up to the point where the error rate exceeds the correction capability inherent in the degree of redundancy in the code, after which the system may resort to interpolation of corrupted data, and that might be audible.

As I have mentioned before, believe it or not, the purpose of error correction is not to correct errors. It is to enable the data transfer bandwidth to be increased by running the hardware so fast that some (correctable) errors are expected to occur. You give up some bandwidth to data redundancy, but you more than get it back by running faster.
