Maintained! Pioneer's pure A grade, completely non-feedback mono power amplifier. Outstanding braking power. The large woofer drives steeply. Later, a straight sound with high transparency and density was achieved with the “Super Linear Circuit,” which is connected to the exclusive famous M5. Although it has a simple design, it is an excellent product that makes a clear and smooth sound powerfully. There is a feeling of use due to aging, such as dullness, small scratches, etc. (Daiki Goto)
