Well, listening to a Sheffield Lab recording, it does indeed sound good,
but I have a theory about vinyl.
Firstly, there is always some undulation in the plastic, this can cause
some dc drift, or rumble or whatever, second, the mechanical sound does
not all transfer to the stylus, the disc deforms, and also carries the
sound at a low level and delays and echoes it back to both channels, which
of course are only isolated by phase in the first place.
Then there are effects in the pick up as well, relaxation of the plastic
as it cools, which is why the audio has to be boosted at hf for a vinyl
master.
All these things do change the sound and can, in some instances fool the
ear that there is far more depth to the sound.


I played a record last night (Vangelis 'The City') with different
amplifiers, one after the other in the same system. The difference in
'depth' between the sound from my SET and the same tracks on my PP valve
amps was quite surprising!

The point is, the whole system is built to 'fool the ear' (into believing
you are 'there,' if nowt else) so I say if it works, then so much the
better.
