I am happy that this matter about the material pressing of vinyl was touched upon here instead of usual the alleged superiority of vinyl which for me in the actual digital state of the technology is only a matter of the cost/design /level of the concerned technology when compared to each other ...
I am happy that this was discussed openly because it was the reason i quit vinyl buying spree BEFORE digital enter the scene ...
As i said when digital came the sound was horrible because it takes at least two decades before this technology was mature enough ...
As an important observation this does not means that all vinyl pressings were bad , at this times i owned a hundred vinyls it is not a big sample enough to gave the right information .... Then i may had been unlucky with my choices and it was half classical and half pop or folk ... This post of mine relate only a limited experience not the truth of the vinyl market at the times...
I remember well why i listened mostly only Bach because i was disgusted with vinyl buyings and not picking the best interpretation first but the more solid and well pressed one .,.. The other reason was my unsatisfaction with the sound quality of my audio system , even with a Sugden Amplifier and Tannoy dual gold concentric ... I did not know anything about what i learned in Acoustics and embeddingas controls in the last 10 years..😊
Then being ignorant my only way to improve the sound was buying costlier component ... But how to improve Tannoy dual concentric and Sugden ampliofier when you are relatively poor ? I did not upgraded ever from Tannoy or any other component i quit buying vinyl till digital ... Upgrading i know it now would had been a disaster because of my ignorance in acoustics and embeddings ...
