That slow roll-off filter along with the tube output stage should sound good with CDs :-) .........
Metronome Kalista DreamPlay Super Slow roll-off filter also shows similar roll-off on CDs :-) ........
If tube output stage is desired, less expensive iFi Audio Pro iDSD DAC ($2,500, reviewed by Stereophile), could be considered :-) .......
If you want something (kinda) more portable, you could look into Sony DMP-Z1, reviewed by Stereophile ......... It has multiple filters including, slow and super slow roll-off filters :-) .......
pretty sure JVS never goes to big "arena" shows for pop/rock music, and clearly doesn't know much/anyting about live sound reinforcement. That's cool (I know you're primarily an acoustic music guy), but don't try to speak to what you don't know.
Oh, and room/speakers/stage volume will have significantly more effect on the sound than the amps, which have pretty much zero audible effect on the sound. Everyone uses the same few brands (Crown, QSC,etc) of class D amps these days. it's more important for the mics to have good off axis rejection and durability than to be "great" mics. that's why it's mostly dynamic mics that you'll see for live sound regardless of venue size.
those concerts include a Grateful Dead Chinese New Year's Show, sitting / standing / dancing in the exact place where all the speakers converged in the Oakland Coliseum - thank you, friends at Pro Home Systems in Oakland, for getting there at 10 AM to snare the sweet spot - the Rolling Stones in I forget which venue, and a number of amplified operas and concerts in Davies Symphony Hall. Way back, I stood 50 feet from Janis Joplin during an impromptu concert in the main park in St. Louis - one of the most memorable experiences of my life - but the volume was turned down on purpose. Oh, and Patti Labelle and the Bluebells in Oakland's Paramount Theatre. Regardless, glad I brought a smile to your face.
JVS may like the Aurender A30, reviewed by Hi-Fi News ........ It has 7 different filters, including NOS type, slow and super slow roll-off filters :-) ........
JVS could review the latest LG V50, 5G smartphone :-) .......
...... excels in quality, musicality, and an analog feel." quoted Jason Serinus.
All roads lead to Rome.
I enjoy the "imperfections" of vinyl (1000+ LPs 95% classical music) for its "quality, musicality & an analogue feel" withOUT need of spending USD50,000 for the medium players.
vinyl, something imperfect, yet 100% analogue without going through the
tedious imperfect analogue-digital-analogue conversion.
