This high-end power amplifier was made in Japan during the golden age of Hi-Fi. This copy was fully checked and tested well. This concerns an exceptionally neat copy! The DENON POA 2400 is appreciated this much because of an open sound with great depth. The basses are tight and well controlled. Denon has provided this nice device with an Optical Class A. This means that at lower volumes, the amplifier operates in Class A, and at louder volumes, it is automatically switched to Class AB. This keeps the amplifier sufficiently cool. With 200 watts at 8 ohms, more than enough power to also drive the more difficult speakers in large spaces. Will be sent perfectly packaged.
