My response has a historical turn to it, because I think the question is the product of its time.
Vinyl was brutally attacked and discredited with lies by the CD's promoters when they needed market share to survive. The CD was only just good enough at that point to replace the vinyl LP for many listeners who had poor-quality turntables. Ironically, the Linn Sondek had only just come onto the market and started to convince a small number that the problems of music reproduction should be addressed at the source. We were not source-oriented before this.
The Linn was expensive. Cheap CD players replaced background noise with distortion in the highs and loose rhythm but these failings were of an order we were not used to. This unfamiliarity was enough to allow many to believe the hype and dump the LP for CD. However the attention that was paid to the source had the result of opening ears to the CD's problems and consequently CD media and playback have improved. Again ironically, if the CD had not appeared the way it did, it might have failed on the market and something with higher sampling rates and longer words, something genuinely competitive with vinyl, might have appeared five years later and convinced many more listeners the LP was dead. Recycling was not then in vogue, so much vinyl which might have been useful for raincoats would have wound up in landfill.
Vinyl and the CD have thus helped each other. The CD was introduced when digital technology was only borderline, barely ready as a music medium. Vinyl has preserved some wonderful music and served as a reference, showing us the promoters were lying. Perfect sound forever, for Pete's sake !
Vinyl and the CD complement each other. One gives more natural music, the other gives us performances we can't get on vinyl. CD is also more convenient to use, and that's good. I think it only makes sense to get into high-end vinyl if you already have a lot of records and you know you want to hear them. However, if you are not satisfied with your CD system and you have bought it using your ears ; if you have looked into room treatment, cables, power supply and component synergy ; if you have heard vinyl do it so much better that you know that's what you want ; then you are condemned to spend a lot of money on a turntable setup and a record collection.
But no reproduction system is perfect and you could instead rest where you are and concentrate on finding software you want to listen to. When there's a critical mass of good software available in another format, you can make the move. In the meantime, if you need to spend more money on music, you could, if you don't already do it, support live music in two ways : go to concerts, and subsidize young musicians to study and purchase instruments.
