"Jim Lesurf"

if the input is genuinely mono then the streams of values for 'Left' and
'Right' on the CD will be precisely identical. Thus if you don't hear a
central image with essentially zero width this is an artefact introduced
by
your replay system (inc speakers and room acoustics, etc).

** Hang on a mo:

Bose 901s produced fantastic "stereo " anywhere in the room - even with a
mono recording !! So too could Sonab speakers - leastwise if the room
had bare walls and no floor coverings.

Both these makers figured out how to turn technical disadvantage into a
MONEY SPINNER !!!!


This may either
be due to an imperfection of the system, or some deliberate tampering to
alter the results, having nothing to do with 'fidelity' as such.


** Yep - one of the tell tale signs of a *very good hi-fi set up* is
that a mono recording sounds like it originates from a point smack between
the two speakers. Plus, if you are playing a mono LP - surface noise will
be in glorious stereo & with amazing width !!

( Leave it that way, resist any temptation to set the pre-amp to "mono" as
it is quite easy to learn to ignore the fake stereo noise as a completely
separate sound from the musical performance you WANT to hear )


May be a sign of a problem (not necessarily in either DAC,
but elsewhere in the listening arrangements).


** The OP is dreamin' ........
