Focal Multichannel Amplifiers Editorial Review
This amplifier seems to be a mixed bag based on customer reviews. One customer mentions that it works incredibly well with Focal speakers and is an excellent upgrade. Another customer found the installation to be flawed and the power output to be far less than expected, to the point of distortion when the levels were dialed up too high. Other customers appreciate the compact size of the amplifier and its ability to power their front speaker systems. There are also reports of compatibility issues with car radios, with one reviewer having to replace their radio entirely to prevent the amplifier from Constantly shutting off. Despite these mixed reviews, customers generally agree on the improved sound quality when properly installed.
