On wednesday 27/1 arrived my Fioo K5 pro and my new TRI I3. I started to play with it and i find an strange behaviour. If I use the usb input all is fine, but if I use he SPDIF IN (or no input connected) I can hear huge hiss with the TRI-I3, if I touch the metal box of the K5 the hiss dissapear but if I left to touch it then again huge hiss. No matter if he Fioo is ON or OFF I can hear the hiss until I keep touched it or conected to and usb source. I´ve tried several plugs of my house and 3 protected strips. The same thing happens with the SMSL M3.
Any help?
