Where is my digital problem: taste, vinyl v. digital, DAC, realities, etc?

I want my digital to sound better.  While I have about 500 vinyl records, I really like being able to sample music first before buying what I know that I will listen to in the future.  I tend, though, to not want to listen as much to poorly recorded music or digital in general.  I'd like to get my digital sounding better to make it more engaging so I can listen longer and test out albums before purchasing.  

Here's what's going on with my digital end versus vinyl.  

Vinyl is holographic--spooky and romantic at times.  The sound fills the space better.  Digital emanates sound more directionally from the loudspeakers.
Vinyl makes certain instruments sound more realistic--i.e. horns, drum sticks, brushes, acoustic guitar/bass.
Vocals on vinyl (in particular when I play jazz vocals from 50s/60s) sound sublime. Digital is not bad, but the vocals sound less in the room and more like a picture of the recording session. 
Digital has more harshness, fatigue, and I cannot play things as loud or as long.  

My DAC is an NAD M51 (fed by Tidal to Bluesound Node 2 to DAC)
My phono pre is a Manley Chinook, taking its signal from a Technics 1200 GAE table and ART9 cartridge.
I seem to get this sound, as described above, regardless of speakers.  

On some level, I haven't spent as much money on the digital end as the analog end.  

Should I try another DAC?  Should I just conclude I'm a vinyl person and live with it?   I'd prefer not to go down the road of getting back into CDs because the beauty of Tidal high resolution is the ability to try out tons of stuff before purchasing the album.

If I try another DAC, what do folks recommend if my priorities are increasing holography, realism of individual instrument sounds, making vocals sound more in the room, and decreasing bite/harshness/glare, etc.   I'd really prefer not to spend Lampizator money.  Can I reasonably achieve an improvement in these objectives by going the route of Border Patrol, a tube DAC, or something in the $2k range?  

BTW, If I didn't love my vinyl sound so much I'd say the NAD M51 is a really great DAC.
