Product Description

Details

The JustBoom Amp comes with an amplified stereo output and an 2x55W peak output. It impresses with its diverse fields of application. What makes it special is the possibility to use the Amp as an single amplifier, but it can also be stuck on top of the DAC or DAC HAT. The needed screws and spacers are included within the delivery scope.

The Amp requires a 2.1mm power supply with 8-24V for optimal usage. If the Amp is used together with the DAC Hat, one power supply can power alll three components: the Amp, the DAC HAT and the Raspberry Pi as well. We recommend using this power supply.

Good sounding AmpReview by Ben K.
Rating
I bought this piece during the discount campaign and added it to extend my existing JustBoom DAC bundle, which really got me. I liked the idea of this Amp and wanted to try it out. The design and the build quality seem to be pretty good. I just have some small Speakers and no other Amp’s to compare with, but I don't need to. For me the Sound, coming out of this Amp is very good and absolutely powerful enough for my needs.
I'm happy with this product and would recommend it. (Posted on 15/12/2016)
