As for the headphone output itself, SMSL stayed vague but announced conservative numbers. With a 32 ohm Load, the SMSL AO300 harmonic distortion reaches 0.003 while maintaining an average signal-to-noise ratio (107dB). A league below the DO400 and even DO200, but the brand top that with the all-new Infineon MA5332MS, which makes the AO300 very interesting.

Why? Because this Class D chip makes the AO300 one of the most powerful speaker amplifiers available in this category, outputting no less than 165W per channel at 4 ohm, and 85W per channel at 8 ohm. Numbers that make the AO300 battling with mid-range amps like the Teac TN-303 – that shares a lot of common traits, but at 2-3 times the price.
