I think the real question is "Why does vinyl seem to sound better to some?"
I think I mentioned this before. Something like 5 years ago, got my hands on a Scott 299B integrated amp. Had a pair of RBH floorstanding speakers, smallish with a 6" mid-woofer and a 1" dome tweeter, a Strathclyde 305 M turntable, SME III arm, Shure 97xE cartridge. I was finding a lot of vintage mono discs in playable condition, had access to an ultrasonic LP cleaner, got a lot of the Frank Sinatra LPs in their first incarnation. The sound was rolled off on top in such a way as to make the midrange pop out and making everything in the treble smooth out. The speakers were too small to have much bass below 70hz so real bass wasn't an issue. The net result made the singer's presence in the room greater when compared to playing the same disc or corresponding CD over solid state gear. I'm heard the same audible Illusion at demos of SET amps with high efficiency speakers. The Scott 299B was on its last legs, gave out within a year. I was lucky enough to be able to sell it at a yard sale.
Based on the gear I'm using now, I have no desire to return to LPs and turntables, all that fussing, all the time the new LP turned out to be badly pressed. But when it was good, it was very good. A different set of sonic flavorings that some will be attracted to, not to mention the inherently greater collectibility of LPs.
I've been wanting to hear the 2015 remaster of Van Morrison's "Astral Weeks" for years. When I was collecting and playing LPs, Astral Weeks as an LP always sounded better than Astral Weeks the CD. The CD is an early issue, like many other analog to digital transfers from the 1980s, the engineers erred on the side of caution, resulting in a CD with lower than average level. The LP also sounded richer, with edges blurred. I'm listening to the 2015 transfer via Amazon Music right now. Everything is more present. But this all depends on memory, which of course is pretty faulty. I know that listening via headphones isn't the same thing as listening over speakers, and there's a thousand other variables thrown in the mix when making these kinds of comparisons. But I'm pretty sure I would enjoy both versions, albeit in different ways.
