Aurender N100H - that seems like a lot of money for what it does. And you are still stuck with USB output to a dac, correct? For a tiny fraction of what the N100H, you could just connect a NAS or HDD to a Rpi and use a I2s to spdif hat or an I2s dac. Most likely, better sound quality as you avoid USB output, works with 32/384 files and you can stream to any other device on the network. This is exactly what Bryston is doing with their Pi player but charging over a grand.
Which server / renderer to buy?
I listen mostly to rock and jazz using a Rogue Audio Cronus Magnum with KT120 power tubes. I listen to both vinyl and digital. My digital streams my music library or Tidal via ethernet CAT6a from my iMac to a W4S modified SONOS Connect thru a Schiit Audio Gungnir Multi-bit ("Gumby") DAC. My speakers are Spatial Audio M3 Turbo S with a Paradigm sub. My room is 17' x 24', but I listen close up - 10' from the speakers / speakers 3' from the wall. I'm considering an upgrade of the SONOS because I would like to stream hi-res and have greater capacity (my library is larger than the SONOS metadata capacity). I'm thinking about the Aurender N100H. Any suggestions? Thanks.
