I got my first shipment of LPs back from Perfect Vinyl Forever today. This included my 14 LP Beatles Collection from MoFi (circa 1982-3). While handled carefully, they were subject to the treatment common for that time which was DiscWasher fluid and brush. Playback was done using my Rabco SL-8E tonearm mounted on a Technics SL-1100A table which served me well for quite a few years (and also illustrates my age). I'm sure there was residue in the grooves from the treatment. I played a few sides today and the LPs had absolutely silent backgrounds with excellent sound quality. I am very impressed and satisfied.
They have also upgraded their Archival process to version 4.0.
