SPECS THAT MATTER
Distortion: inaudible; 1000x lower than any transducer (speaker or headphone) you're using
Noise: inaudible; far below a typical speaker power amplifier
Input capability: accommodates all actual music recordings (upsampling for the heck of it, maybe not), up to 2 USBs!
Heat: runs moderately warm; this is normal and no need for panic
Size: suitable for typical stereo shelf or rack placement, not desk-friendly
