What is the actual percentage of people exclusively listening to vinyl vs digital?

I’ve never had anyone who listened to something on my system - first in vinyl and then digital - say that they preferred digital. Instead it’s usually this: “The first sounded more open and realistic...”

@mglik " To me, it seems strange when auditioning “$100Kish gear, that vinyl doesn’t enter the picture or conversation."

Because, from a capability standpoint, vinyl is technologically inferior to digital.

Additionally,

• Vinyl has pops, clicks and hiss ( I grew up with vinyl and this is why I dumped it)
• Vinyl is way more expensive
• Vinyl players (turntables/cartridges) are way more expensive
• Vinyl takes up a lot of space, whereas my whole library fits on a flash drive
• Vinyl isn't portable
• Vinyl wears
• And vinyl is obviously less convenient (my digital system is voice-controlled, and starts and plays with two commands)

So it's not a surprise to me that vinyl wouldn't be a consideration. What is a surprise is that anyone would spend $100K on a system when Revel Salon 2s are only $20K.

As for percentages, the most recent stats I saw show vinyl at less than 5% of the market. I think vinyl will follow the trend of other nostalgia and die out when the people who grew up with it are gone.

I suspect youth are a large part of vinyl resurgence. For those who've grown up with digital, vinyl is a novelty. The large format of vinyl, album covers and gatefolds with unique art and words of interest make music contained within more personal and important. I recall these feelings flowing through me from back in the day.  Would Sgt Peppers have been so important and magical without all wonderful art and words on cover and gatefold. The large format allowed me to connect and gain insights into artist. I recall gazing upon art and words even as I listened to music, vinyl was a total immersive experience. And then you had the advantage of intrinsic value of vinyl, something to hold and touch, something of value, something to care about. Perhaps all these feelings are what is drawing in new converts to vinyl.
And for many of us older audiophiles, the advent of digital and cd's became a novelty. I recall the technical allure of digital, all this convenience, small format perceived as advantage and more magical equipment to purchase and experience, I was all in! 
And then along comes streaming, wow, the technical allure was even more intriguing for me, so much to learn! Over time as I gained some mastery over this format, I recall the feelings of great accomplishment as so many complex problems were solved. The diy experience of this format has been a great allure for me. And now that I finally have an optimized streaming solution, I'm loving the amazingly wide variety of music available to me from simply pressing buttons on a smartphone device! I've been exposed to far more music than I would have been sticking exclusively to vinyl or cd. I'd have to say streaming has turned me into much more of a music lover than audiophile. Rather ironic a format many think is less emotionally involving and immersive has turned out to be quite the opposite for me.

I recently went to a direct ethernet connection streaming to my Devialet Expert 400, figuring this is about as good as digital gets, at least for my money. I am delighted I can finally listen to digital as a source instead of just background music. Still, when I play an album on my old VPI HW-19 Mk IV with Eminent Technology 2 tonearm and a Monster Cable Sigma Genesis cartridge, it blows the streaming version out of the water.  No contest. 
I admit I now listen mostly to digital because of its convenience and selection, but when I want to be enveloped by the music, I fire up the turntable. Digital is becoming a closer second, but it is still second. The good news if I don’t know what to expect/listen for, digital sounds great. It’s come a long way since the 80s.

mambacfa, in order to compare sources like that you have to switch back and forth concentrating on one detail at a time. 

Over the years I have noticed that what people think sounds best has much less to do with accuracy than one would think. In some situations "accurate" actually sounds worse! This is very relevant when it comes to room treatment. As always beauty is in the eye of the beholder. A system that "sounds good" playing everything is most likely stamping it's own signature on everything it plays. There are plenty of terrible recordings out there both digital and analog. The vagaries of speaker performance far outweigh any differences between digital and analog playback.
The preference of one format over the other is most likely due to other factors besides sound quality. Number one would probably be convenience.  Insisting that one format always sounds better than the other. Very few issues are "always."
