I tried Factory reset, also does not help.

It doesn't help. In Device Settings: Your Poly is up to date. Version 2.0.4

The 2.04 version is installed. The 3.0 update button in the settings is inactive. How to fix it?

Maybe someone was comparing Meier Audio StageDAC and MHDT Havana DAC? What conclusions? Which of them will be better for the Stax SRS-3030 Classic System?
