After weeks of re-examining the Spotify Connect SDK and its interfacing with our architecture, I’ve been able to find several areas for sound quality improvement for Spotify Connect.
This work is now released in Firmware 15.3, and will be gradually released to the whole Lumin lineup.
For Spotify, I believe that we surpass those competitors that only did a standard integration.
I encourage users to create a Spotify Free account and try it out. You may be able to discover new music to your liking with it. Note that only streamers with certified and authentic Spotify SDK can play Spotify Free - those competitors using the open source reverse engineered library cannot.
A word of caution for those who connect their Lumin devices directly to a power amp: when I updated to firmware 15.3 the volume control reverted to 100 percent. If memory serves me, other firmware updates kept my original configuration (80 percent volume setting).
