As class D amplifiers take over the small low cost amp market, amps like this are beginning to surprise old school hifi enthusiasts who have ignored them too long. This compact amp has an HDMI arc input and it's own DAC tied to a USB C input, allowing it to serve as a two channel sound source for your TV or your computer. It has RCA inputs to connect your old school stereo equipment, and bluetooth to pair with your phone.
