SiriusXM signals have very limited frequency response - at best, 7.5 kHz. If you want to try a station with practically no processing, try discoverclassical.org. They only limit the loudest output so it doesn't go into digital distortion. Another good stream is that of AllClassical.org from Portland, OR. KCSM.org has a good sounding Jazz signal.
Why Streaming Service Sounds ‘Flat’ vs Tune In /Local FM /Radio Paradise
I use a Bluesound Node, first or second gen I believe.
I use the S/PDIF output feeding my Esoteric K-07X CD/DAC using it as a DAC.
I find that CD’s, most things using Tune In, and local FM listening sound better than streaming either Tidal or Qobuz.
For the life of me, I can’t figure why that might be, since all are using the K-07X internal DAC. I can understand the CD, as it’s internal, with no S/PDIF cable to possibly muck things up. FWIW, I’m using the Illuminati/Kimber D-60 as my digital cable.
Any thoughts appreciated.
