He’s currently using it to power his near-field monitor system in his editing suite, paired with an SMSL Raw MDA1 DAC/preamp. Bob notes that the system sounds quite full without needing a subwoofer due to the close listening distance.

Bob walks through the front panel controls, highlighting the stereo/mono switch that also serves as power, a subwoofer frequency control (though unmarked), a super bass boost, and separate auxiliary and master volume controls.

Summary

In this portion of the review, the host from United States of Analog begins outlining the key benefits of the DOUK Audio A100 Mini Power Amp. He mentions upfront that the channel doesn’t pay his bills and he has a day job, but he’s trying to keep reviews concise. The amp features the popular Texas Instruments 3255 chip, which he describes as the workhorse of the “FunFi” category, and is rated at 300 watts per channel, though he seems somewhat skeptical of this specification.

The host highlights several standout features including the amp’s flexibility to work in stereo or mono configurations, a useful auxiliary output for connecting various devices, and the inclusion of a 48V power supply instead of the typical 32V. He suggests this higher voltage supply could potentially upgrade other FunFi amps in users’ collections. The build quality appears solid with excellent heat dissipation properties, with the entire chassis acting as a heat sink.

Additional features include swappable 8-pin op amps, though the host admits he hasn’t experimented with op amp rolling yet, calling himself “a loser” in a self-deprecating manner. He emphasizes that for his current editing setup, the amp performs well in its stock configuration. The host concludes this positive assessment by noting he’s about to transition into discussing some downsides and nitpicks, though these aren’t covered in this transcript portion.
