  1. Phenominal Amp 5 Star Review

    Posted by on 3rd Mar 2021

    Amp is consistent, powerful and clear. The power delivery is consistent. The adjustable gains are precise, build quality is superb. Footprint is small, welcomed edition to the build. But it and you won’t regret it!

  2. Classy compact amp. 5 Star Review

    Posted by on 3rd Nov 2020

    Great amp. Stays cooler than my symphony S/800.4 which is the previous model. And way smaller. Small foot print. And so versatile. Great amp for a good price. I’m so glad I found this amplifier. And I love how small it is.

    Upgraded from a pioneer GM-D8604, huge difference in clarity and mid bass. Love this amp, highly recommended!
