DAC failure?

Was listening to some music this evening when suddenly the output dropped to about 25% and the sound turned really static sounding.

The Dac sits on it’s own shelf with about 16” of air space above it, but it was extremely hot to the touch..

After checking a few things, I switched to my R2R DAC and everything sounds normal.

Has anyone had a DAC fail with these symptoms?

I’ve sent an email to the company that makes that dac.. just curious if anyone else ever had it happen and what their issue was finally diagnosed as.

thanks
