I only buy music on CD's. The sound is not quite as "pure" as vinyl, but they do not degrade like vinyl does when you play them. Most new music is probably recorded digitally, but I haven't bought anything recorded in the last 30 years. I've ripped all of my music to MP3 to play in the car and share with the family. My CD's are in a locked cabinet and only I touch them. I have an old higher end CD player, and I believe the sound quality is better than MP3's. There is compression etc involved in ripping MP3's. Only I touch my CD's.These days, I have a shit-ton of Audio CDs and DVDs (and now Blu-Ray). I guard those religiously.. And I maintain players for each form of content. I even have one of the original Sony "Discman®" mini players. And, believe it or not, I still have an old Sony "Betamax®" VCR as well as VHS players.
Vinyl has become "cool", but I have to laugh at the new USB turntables. Most of the music I like was recorded in analog, and vinyl purists are looking for the warmer analog sound. Immediately running the sound into an A-D conversion is just not pure. Some albums from the 80's were recorded, mastered, or remastered digitally, and putting them on vinyl seems stupid.
I'm not that much of an audiophile and accept the sound of CD's. MP3's are OK for the car and providing background sound in the house. When I really want to listen to music, I go to my CD's.
