Digital Assistance Required

I normally don't listen much to CDs any more--prefer either vinyl or streaming with Roon + Tidal.  However, several years ago my wife bought me the Neil Young Archives Vol 1--pamphlet of which says recorded in HDCD at 24/192--which immediately confused me because i thought HDCD was only 20 bit depth--but that's not relevant so much.  Anyway, i have an old CD player/recorder--Pioneer PDR-609--when i do play discs.  I have two DACs--an Aesthetix Pandora and a Mytek Brooklyn--i use the latter mostly for vinyl, MQA and headphones and the former for everything else digital and it plays 24/192.  Sooo-  I thought that if i use the Pioneer to play the Neil Young discs it would send the 24/192 to its coaxial digital output (it also has a Toslink output) and i could then send that to the Pandora DAC and it would play 24/192 the way Neil intended.  Sadly, no--the Pandora display only shows 16/44.1--which is actually still pretty good but...so what am i missing here ?  Do i need a DAC that has an HDCD-specific chip to decode that information?  Is the Pioneer not actually sending 24/192 to its digital outputs ?  Should i try to send the Pioneer coax to the Mytek ? (Big Hassle but do-able)--I just want to hear if there's a difference between 16/44.1 (as Neil firmly believes) vs. 24/192.  Appreciate any help--if it turns out that i have to purchase a new CD player i will not do that just to listen to these CDs--they are the only HDCDs that i have.  Ditto for DAC.  Thanks
