“Is there a better way for digital playback…..
As you know better is subjective and any given component must gel (synergy) with rest of your system for one to say, I prefer the brand X better than brand Y. I found a component last year that not only simplified my digital streaming but also transcended my existing digital front end (EMM Labs DA2 / Aurender N20). I suggest you to look into Merging Technologies +player. It’s a DAC/Roon player/Preamp, all in one box. No external component needed to run a Roon core. All you need is one high quality LAN cable, which you already own.
BTW, I am quite intrigued by your Manger S1 speakers, what made you decide to go with powered speakers over passive ones in Manger speaker line up?
