Luxman L-507u Integrated Amplifier

A preamplifier with a rated output of 200W (at 4Ω load) class AB. The latest version 3.0 of the unique high-quality feedback circuit ODNF, which has a parallel error detection section, is used for the first time in a preamplifier at the center of the amplifier section that controls the sound quality. The low impedance of the error detection circuit has significantly improved various characteristics such as distortion rate and S/N ratio. A separate switch is used to separate the preamplifier and power amplifier.
