In many cases, I cannot tell tthe difference between a home made cd of a
vinyl and the real one. The only time it notices is if you go overboard with
click suppression or rumbe and other noise reduction as on dying echoes you
hear the watermark effect or the little blips in level where the click used
to be.


However some of the early recordings I made when DAB was still relatively
new sound much better than a repeat of the same material on the same station
escpecially if that is radio 2. it seems engineering on that station is now
a gain riding auto level control and a compressor.

Yes, it absolutely is about psychoacoustics, not actual differences.
That's why it is important to eliminate it.
