Things to Know
- ⚠Built-in battery is unnecessary for a desktop unit and will eventually degrade/fail.
- ⚠Input is limited to a single 3.5mm jack (no RCA inputs without adapter).
- ⚠Form factor is tall and narrow, making it easy to tip over when heavy cables are attached.
Reviews
“The loudness function, particularly rare in mini amplifiers, is present here. I love so much the effect it provides that I leave it on all the time... boosting bass and treble inversely proportional to the output level.”
— AudioScienceReview (Djano)
“The amp provides an impressive amount of separation for a unit of this price range. Bass enthusiasts will be satisfied with the amount of bass that can be elicited.”
— Fosi Audio Blog (Review by Dr. David Geier)
