It must be very sad to believe that everything we find attractive in this hobby is an artefact or coloration
Ah yes, but not sad, just understandable,
As I said this was only with old stuff Beatles, Beach Boys ect. that was recorded and voiced with no digital involved, and where the "channel separation null’ing network" worked a treat with digital.
With later stuff recorded and voiced on digital equipment, the null’ing circuit is definitely better left out, and to me far better through the digital gear, and not through vinyl.
