I have a Presswell copy with narrow deadwax on side 2 that is Mint-[I have several period copies including the old Mofi]; the Monarch is supposed to be the "bomb" but I don’t know if there are any white label promos pressed by Monarch. They changed the mastering pretty fast, though by standards of the industry, they pressed a ****load before they changed the mastering.
The UK plum (by definition, early) is equally bass-y but doesn’t have the high frequencies of the RL.
As to Better Records, no comment. :)
I have a copy of Free’s Tons of Sobs from them and it is the best sounding among three copies here, though I don’t have a first. (bullseye pink).
