I have an RSD pressing of The Doors called curated for record store day. It was pressed at QRP, and all songs on side one are mono. I think it sounds fantastic on my stereo cart. That said, I am sure it would sound better with an equal cartridge that is mono. As to the technical reasons why, I will leave that to those with experience.
will new Beatles mono lp's require a mono setup
wondering if the new Beatles mono set will necessitate a true mono cartridge and so on, to sound right. That is not so common today, even among audiophiles.
