Continued claims that vinyl has to have mono base abound presumably to convince some people CD is 'perfect sound forever'. Similar to denials that hi-res can sound better than Cd's 16/44.1. Anyway I came across an interesting post on SH forum by well known mastering engineer Barry Diament.
So though it is done I am not hearing things on some records when bass appears in one channel or the other.robertash, Feb 9, 2007 Report#3Like+ QuoteReply

We discussed this here just in the last week; Barry Diament expressed that this was indeed one of the concessions made to make a master ready for cutting.
Now, I don't remember if he told us this was done by the producer preparing the master itself, or if it was solely the responsibility of the mastering engineer at the pressing facility, so I don't recall at what stage this tweak was added.
Hi Dillydipper and Robert,
This is done during vinyl mastering. It doesn't have to be done. It just often is. Much as compression doesn't have to be done. It just often is. Neither is done on the very best records (despite some folks' belief that one or both must be done).
I've known engineers that would mono the signal as high up as 150 Hz!
!
Best regards,
Barry
