Denon is one of the rare audio brands that continue to actively develop Hi-Fi components and accumulate, refine, and pass down Hi-Fi audio technologies. The 2500NE series, designed for today’s age, has been developed by both veteran engineers and talented young engineers who have inherited the Denon technologies and expertise that have been cultivated over many years and decades. And the performance of the PMA-2500NE goes well beyond that of Denon’s previous PMA-2000 series. With its ultimate built-quality, unique Denon technologies and state-of-the-art connectivity, the PMA-2500NE truly is a masterpiece of sound technology. Thanks to the rear USB-B input and embedded high quality D/A converter, the PMA plays high resolution files up to 384kHz/32bit and DSD up to 11.2MHz from a computer in impeccable sonic quality. For the best performance from analogue inputs, the PMA features an Analog Mode which allows to switch off all unutilized sections like the digital input circuitry or the low noise display for an unaltered audio reproduction.

Denon is one of the rare audio brands that continue to actively develop Hi-Fi components and accumulate, refine, and pass down Hi-Fi audio technologies. The 2500NE series, designed for today’s age, has been developed by both veteran engineers and talented young engineers who have inherited the Denon technologies and expertise that have been cultivated over many years and decades. The DCD-2500NE focuses on achieving the essence of a disc player: ultra-high precision in reading discs and supplying high-quality audio signals to the amp. To achieve this, the signal paths are as short as possible and the whole circuitry is minimized. The engineers also redesigned the disc drive mechanism brackets and the chassis to eliminate vibration, the great enemy of disc players, and achieve ultra-vibration-resistant performance. The information on the disc is now read with impeccable accuracy and a clean, high-grade signal is supplied to the DCD-2500NE’s Advanced AL32 Processing Plus circuitry. Besides CD and Super Audio CD playback, the DCD features playback of audio recordings up to PCM192/24 or DSD5.6 recorded on a DVD R/RW for full flexibility and extended access to high resolution audio.
