Eversolo FW and support are pretty bad in my experience. Lot of money to spend for decent hardware and non existent support.
I've been waiting over a year for them to correct an issue caused by FW . USB won't recognize a DAC it worked perfectly with for a year. The last FW recognized DAC but no sound. Fortunately there is a coax output as well. Thats not a fix though.
The worst company I've ever dealt with in 45 years of this hobby.
