    I bought 2 amplifiers one 4 channels S4-100 and one monoblock S1-1250 and I’m completely satisfied, my rating is 5 stars. Excellent build quality, excellent sound quality, small but heavy and I liked the clarity and working cool. 100% recommended also the shipping was super Faster only one day. Fastttt!!!! Really I’m satisfied, I’m a new fan boy of SoundQubed

    I love this amp! It is compact and pumps out plenty of ultra clean power. Its driving my 4 mid/highs coaxials and I’m just simply impressed with the performance it delivers.

    What a beast of a little amp. Have it on (2) Image Dynamics 6.5 components and they are loud and clear!
