According to the manual, which I'd advise you to download and read, the inputs can be routed directly to the outputs.
In AudioFuse Studio manual, page 11, about phono inputs:
"These inputs connect directly to the AudioFuse Studio's pristine analog-to-digital converters"
Please clarify which page of manual for any of the AudioFuse products specifies that phono inputs can be routed directly to output without going through conversion to digital and back.
