Mainliner: 'Mainliner Sonic', although I believe it was a calculated maneuver to replicate the sound of your speaker cones imploding upon themselves.
I've owned (and sold) some pretty crappy mid-'80's digital transfers of early jazz recordings that were pretty nasty...most recently, I was bummed out by a two-disc Ellington CD set that sounded as if the soul of the music had been forcibly wrenched out.
The worst case of bad digital transferring was evident in a set of Greek rebetica recordings transcribed from '78's and metal discs from the early part of the century. Intolerable...sounded like you were listening to a TV speaker playing from another room. Granted this is a tough task, but I own a few discs of music from this vintage that are actually quite nice. I imagine that you just have to CARE about the music you're processing to do it justice.
