This thing is powerful and so easy to integrate into a gig where passive speakers need power. Gunna upgrade to the 48v power block and the 2.1 version to also power subs

A great little amp. I really like have the knobs for bass and treble on this little unit. Doesn't get overly loud, but it's a good Class-D amp. I'm using on my desktop.

For curiosity, i spent almost $200 for this unit to hear if what they say about is true. True it is. My full size speakers can sing now. I love it.

Little amp is unreal. I've compared this to a SABAJ A4 and an older early 2000's model Yamaha AV receiver amplifier. I have this amp pushing two JBL (Venue?) Stadiums. they're 8 ohm speakers so they're only getting half of what this little amp is capable of dishing out and the sound coming out of this thing is unreal. it was almost 200 CAD by the time it got to me (I got the beefier power supply off of the Fosi website) and yeah. I'd do this again.

i am giving this a 4 star rating -- as it sounds good (out of the box) and is providing excellent power to my 2 TV Speakers. This amp is definitely worth a listen (and the 2 tone controls work well -- providing a subtle shelf to the bass and treble).I am impressed with the sound quality from this little amp -- Now it is not going to replace my high end gear -- but for the money - it is impressive.I have not tried OP am rolling -- but will look into that , let the amp burn in a bit.Highly recommended!

This product is awesome. It pumps out a substantial amount of of power to the speakers… and the Bluetooth connection is solid as a rock. This particular unit also has a “pre” output which will support a subwoofer.One area I would caution about is the indication that if one changes out the power rectifier from a 32V to a 48V unit, you will increase the total power output to the speakers. This may work in theory, but in practice…there is a decent chance that you blow up this unit.This notwithstanding, this small unit is an absolute game changer… not only in how it saves you thereal-estate on your desk…but that it does so with crystal clear sound.
