The P-1R monaural power amplifier is an upgraded version of the existing P-1, employing a new power supply unit design featuring a large-capacity electrolytic capacitor for an increased sense of bass frequency speed and force and a major overhaul of the component parts to provide greater musical expressive power in the treble range. These two improved elements combine to make the P-1R Bewith’s flagship power amplifier model. The discrete configuration power amplifier circuit continues the Air Circuit concept’s emphasis on sound quality as the top priority and employs elements jointly developed by Bewith and New Japan Radio, including the BSZ1 acoustic dedicated operational amplifier and MUSES7001 large-capacity acoustic SiC (silicon carbide) diode. The P-1R weighs in at only 645g thanks to its MAGNEOLA acoustic magnesium alloy body, unique low heat generation/low power consumption technology and a stylish exterior design that features heat radiating fins. The exterior is coated with a new vivid and deeply glossy Sunrise Red clear gloss paint finish.
