small, neat, well built and great sound,
Title says it all really.
I've got it stuck to the back of a Samsung Smart TV which (of course) only has an optical out or a 3.5mm headphone jack. Quite why the TV doesn't have RCA o/p sockets is beyond me...
Slightly annoyingly (but no fault of the DAC), the TV's Toslink output cannot be volume controlled from the TV remote; so the amp that I'm feeding from the DAC has to do the volume control.
Sound is much clearer from the DAC than it is from the headphone jack.
The DAC has a UK plug-top USB power adaptor, but I'm using one of the TV's USB ports instead.
