Best Audiophile Album in terms of Dynamic Range and Mastering Quality?

What NEW records are you speaking of? No new performers are using anyone of quality to make a record. So to answer your question: Eric Clapton's Unplugged (RTI) is one of the best sounding records you can lay on a turntable.

Good list- people getting into audiophile-ness should bookmark it. 

Yes, there are many new albums just as good- go to NativeDSD for an example- Patricia Barber's Clique is as good as it gets for sound quality. I much prefer many of her previous albums for musicianship over Clique however. 

This is great!  Thanks for sharing.

The question, posed many times, has been answered.  While you may not agree with all of their choices, look to The Absolute Sound Super LP List and the annual Stereophile Records to Live For  (pre covid name Records to Die For) lists.  All listed albums are generally excellent performances and mastering worthy of system demonstration. The list includes old, old/ newly remastered, and newly recorded albums.  Some of my favorite newly recorded albums to demonstrate my system capabilities are:  

1. Classical:  Boarders, Henning Sommerro, Trondheim Symphony Orchestra, 2L Records 2L-173-SABD.  Modern classical, natural timbre, dense imaging, wide and deep staging, phenomenal clarity, excellent bass extension and excellent dynamics.  
2. Pop/Rock:  Cunningham/Bird  Loma Vista Recordings.  An excellent, Avant-garde take on the phenomenal compositions on Buckingham Nicks, a pre-Fleetwood Mac vinyl record now out of print.  All of the same qualities as #1 but in this genera. 
3. Pop:   Any of the three Billy Eilish albums.  You may not like the genre or all of her music, but if you are looking to demonstrate your system from a studio engineering effects perspective, you have to complement the recording engineering team. 
4. Folk:  Katja Werka, Contact Myself 2.0, Stockfish Records SFR 357.4102.2, OK it’s not newly recorded, but many do not know of the artist or recording.  All attributes of #1 in this genre.
5. Jazz:  Echoes Of The Inner Prophet, Melissa Aldana, tenor saxophone, Blue Note Records/UMG Recordings 00602458277470. It’s a Blue Note mastering.  I do not need to say more.  
6. Big Band:  BENNY GOODMAN - LIVE IN HAMBURG 1981" ANALOG PEARLS VOL.5, Stockfish Records, SFR 357.4806.2 recent, excellent digital remaster of one of the band leaders that defined the genera.  

Interesting list - reminded me of a few albums I need to listen to and a few that will never grace my rig no matter how good they are recorded. 
 

I am stunned that no Grateful Dead albums were on the list (unless I missed them). Both American Beauty and Working Man’s Dead are exquisitely recorded/mastered. Likely other dead albums are as well - these are the 2 I’m most familiar with and what I play to demo my rig.
