but having opinions is an art.

Stuff from J. Audio Eng. Soc., 3/84:
On Dither (Vanderkooy/Lipshitz) --
Yes, Virginia, dither really does make a digital system behave like
analog for low-level signals. Doug Sax would hate this study.
On CD Phase (Meyer) --
Mr. Meyer constructs and sell boxes to linearize delay. Because of
this, I am somewhat surprised that an academic rag (ah, but it is an
"engineering", as opposed to an "acoustics" journal) would print his
subjective conclusions, without double-blind tests. Actually, his conclusions
are rather mild, i.e., that first-generation CD recorders audibly muck up
phase only under extreme conditions (impulse trains & live recording, but
not typical program material). Those who listen to the music and not the
noise (like me) would consider Meyer's box another piece of "parasitic"
engineering, typical of the snake oil history of high fidelity.
