My vinyl collection is at least 90% pre 1990's purchases or gifted. While some of the newer vinyl has great sound, some is digital original mastering or remastering, pure analog masters, no digital ever sounds best to me. Vinyl prices would certainly be an obstacle for those just starting a vinyl collection.
There have been times when I've thought about liquidating my vinyl, tempted when I see prices of used vinyl. Since I purchased cheap back in the day, this has turned out to be good investment. The question is does the benefit of playing vinyl outweigh the financial gain of liquidating? Financial gain of liquidating entire vinyl setup also part of equation. I either need to upgrade vinyl setup big time or walk away. I bet any number of audiophiles have come to this place and decided to sell off vinyl. The better digital gets the more will come to this realization.
