Are you asking if MoFi Abbey Road LP is flat? If so, I'd have to say no. It seems goosed a bit. I began with a Capitol (likely Jax pressing) US LP. I had compared it to the UK LP from blue box. Preferred the UK mainly for quieter vinyl. The MoFi is even more quiet. Not a flat transfer, but MoFi is my go to vinyl copy.
I had the individual MoFi LP a year or two prior to MoFi box. They are the same LP sound wise. LP sleeve is different in box. Pix of notes on master tape boxes.
I had 250 w/ch separates and an MC20/MCA 76 Ortofon late 70's/early 80's. Still use a more recent MC20. Cartridge is a bit zingy, which I like
My most listened to Abbey Road is Toshiba/EMI Japan CD. Got it and the next week it disappeared from circulation. Years before their CD roll out. BTW: original US & UK CD's sound identical to Japan CD from '83.
Copies I bought: US LP, blue UK 2ch LP collection, mono UK LP red collection (AR & Let it Be are foldovers), MoFi LP single, MoFi LP box, Japan CD, US CD, UK CD rolltop box, US remaster black box, & super deeluxe AR BD etc box.
I haven't a/b'ed every AR to all others. Hopefully, the ones I mentioned provide the insight you're seeking.
and Abbey Road is one of my 10 favorite albums.
