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

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." 

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)

Interesting post...

I use only digital myself...

But you forgot the main reason why vinyl subsist with success for many people owners of the 2 system, digital and vinyl...

The room acoustical bad controls of most users reinforce the choice of vinyl because vinyl S.Q. format resist more to a non optimal acoustical room settings...Digital to shine ASK for optimal acoustical controls more than vinyl, because of the technical aspect and measured potential performance of this format...

And unbeknownst to most, almost all rooms are not optimally acoustically controlled....It is impossible to realize for ourself this fact if someone had not experience it first hand...Acoustic is the true key to audiophile experience especially for most people who dont own a million dollars system ... Anyway some one million dollars system sound bad it is easy to look for some example in youtube....

In a room acoustically well controlled if the difference subsist it takes very refined audio system to detect the difference if one exist....And this is a minute difference....Mike lavigne experience and testimony for example....For ordinary mortal with average system the key is acoustic controls not the choice between these 2 formats.... I own thousands of files.... It is impossible for me  to own thousands of vinyls in a room dedicated only to the object....And most music that interest me is not on vinyl anyway.... Iranian-Indian-and other people music for example or non commercial or not well known jazz music....

If you listen pink floyd mainly no problem to keep also only few hundred of vinyl on repeat..... 😊

 the choice of music is way more extensive in digital format and more accessible...

Until I see the survey results, I assume ZERO!  There are digital stations in our cars, on television, and who has not owned a CD player, especially in a car?  Maybe you mean on our best home system?  Maybe juke box owners?   Maybe I amazed....

I have two systems with turntables plus a server with about 4000 CDs on it (I have a similar number of LPs). For casual listening, digital gets used more. For listening sessions, it is probably 75% analogue for me.
