Better Records’ Tom Port obscures the pressing info contained in the run out groove of the LP’s he sells by adding his own scratches (not cool, imo), in order to make identifying a white hot stamper (as defined by him. When I visited his apartment in the early-mid-90’s, his hi-fi was decidedly mid-fi---a receiver, record changer, and bookshelf loudspeakers. Perhaps he has a more transparent, resolving system today. Or perhaps not. Rare record dealers are most often not audiophiles) impossible.
RL pressings of LZ 2 are not that that to find; I found one in VG+ condition locally for $40. Was it a white hot stamped pressing? I don’t know---I’m not a fan of LZ, and left the LP for someone who is. Unlike TP, I’m not a greedy pig.
