Yup, the SQ of the vintage vinyl is all over the place, ie. 60’s & 70’s. This is why you have those websites where afficionados have done all the research to identify the best pressings. As digital came into the mix, Vinyl and CDs started sounding the same. So, for me, past the 80’s, I rely on digital (CD, SACD, .wav files, .dsf files, and Streaming) for my music.
So, in my opinion, if you are looking for Vintage Vinyl, quality is better than quantity. Research the best pressing and get "EX+" or "Mint", and you will always have the urge to play that album, and it will sound better than the CD.
