My DVD player and my digital reciever have both coaxial and optical
jacks. Which connection should I use to get better sound quality or are
they all equal?

The coaxial connection is superior, although modern digital receiver chips
have narrowed the difference.

In the service manuals for certain digital preamps, Sony instructs that
the adjustment for harmonic distortion must be performed with a signal
source delivered by the coaxial input. This shows that in some cases, the
digital input receiver can suffer with an optical connection, in a
measurable way.


No it doesn't. I shows Sony have more faith in the integrity of any form of
coax over the variable quality of (potentially cheap-and-nasty) optical.
