Pros: Audio Science Review measured a SINAD of 111 dB, clean for nearly all listening. It is rated for 1,000 mW into 32 ohms from the 6.35 mm jack and 700 mW from its 4-pin XLR balanced output, enough for most planar magnetic headphones. It adds XLR and RCA inputs and outputs, a motorized volume knob and a learnable IR remote.
Cons: Its USB, coaxial and optical inputs require an optional DAC module, so digital playback costs extra. It costs far more than the JDS Labs Element IV, which rates higher, measures cleaner and has more rated power.
