#7 MOTU M4: $279.95 Amazon $279.95 eBay

Pros: Audio Science Review measured 111 dB SINAD from its ESS Sabre32 Ultra DAC, clean for nearly all listening and competitive with good budget DACs. It adds two balanced line inputs to the two XLR/TRS combo inputs, has four balanced TRS outputs with mirrored RCA outputs, MIDI in and a hardware volume knob, and Audio Science Review found its recording converter better than many computer interfaces.

Cons: MOTU doesn’t publish a 32 ohm headphone power figure, and Audio Science Review measured just 18 mW into 300 ohms, calling the headphone amplifier its weakest part, so demanding headphones may run out of volume. The Topping M62 rates higher for less.
