Yes, you're quite right, breathing WON'T show up on dbx encoded LPs because the
source noise level is so low.  I have a couple and the reproduction (harp) is
flawless.  But Mr. Francois is talking about duping NORMAL LPs to tape through
a dbx compander, which is a different case entirely.  Here the signal level is
much closer to the noise floor, and breathing is almost inevitable.

Mr. Francois' unit was not misadjusted, since my recently recalibrated 228 will
do and always has done exactly the same thing on certain program material.

I agree with Mr. Mitchell, however - dbx is the best thing since sliced bread
for tape recording live music in particular and LP duping in general.  It
offers the recordist many more options and higher performance than Dolby with
far less sensitivity to deck-to-deck calibration errors.
Unfortunately, given the poor quality of even the best non_encoded LPs,
Dolby C may be a better practical solution to tape deck NR when recording
critical material (piano, harp, etc.) from this source.
(An aside: this may be why Nakamichi has never jumped on the dbx bandwagon.)
