Here's yet another vote to move on from Spotify.
I used a M1 Mac Mini to feed my DAC for several years and got some pretty great results. But, of course, everyone says to get rid of the computer (I'm a Roon user) so I tried the Eversolo DMP-A8 and could hear no improvement at all. So I sold it and got the HiFi Rose 130 and holy cow, this was a HUGE improvement. I feel like this unit is often forgotten about here as most will recommend Aurender or Innuos, which I have no doubt are excellent but the RS130 offers fantastic, possibly even transformative sound AND a much nicer and more user-friendly form factor. Also has I2S output, which I'm now a big believer in. If something happened to mine I'd buy another one immediately.
I'm currently running mine into a PS Audio DS Mk 1 and while it sounds really good, I have ordered a May DAC from Holo Audio and expect another big jump in SQ.
I've never heard the "lesser" products from HiFi Rose, which all include a DAC, but I suspect there's something special about the 130.
