The BR website currently has two copies of Beatles for Sale listed at ~$170 & $300 (rounded up one cent), so I pulled my copy off the shelf and gave it a spin.
I rate both sides as "Mint Minus" (BR term, $300+), with just one light tick in the dead-wax. [Sonically it is compressed, but after all these years I still get lost in the fun/beauty of the music.]
Then I recalled hearing more noise during previous playings. So, what changed? (It was not cleaned between playings). I recently installed a better cartridge. More specifically, I moved from an elliptical stylus to a micro-line stylus.
A friend told me to expect quieter backgrounds, and he was right. Moreover, this was not an isolated incident. Over the years I have kept play-grading notes, and now each LP seems quieter (as compared to my notes).
I have a large LP collection, and at $300, I would need to spend ~$1M to replace all of them. A better stylus is not a 'cure all', but I am glad I upgraded my cartridge instead of replacing excellent LPs.
