Steven C. Barr

The playing of an analog recording need not produce "measurable" degradation. 
With magnetic tape it is the buildup of noise and distortion through multiple 
record-playback cycles in mixing that degrades the result relative to digital 

Playing a clean record with a modern stylus would have to be repeated 
hundreds of times for the degradation to be measurable. Meanwhile, the "New Products" 
section of the current (October) issue of "Pro Audio Review" reports the 
reintroduction of the ALP Laser Turntable, list price $15,000.00.

The handling and storage of the media that are responsible for most of the 
degradation. It is the error correction feature of digital media that it 
possible to store audio without degradation over time ... until someone forgets to 
backup and it is completely gone forever.
