The Denon is one of the rare audio brands that continued 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.
Advanced UHC-MOS Single Push-Pull Circuit:
To achieve impeccable balance between delicate details and vigor in sound, the PMA-2500NE employs Ultra High Current MOS (UHC-MOS) FETs, capable of producing ample current in a single push-pull configuration which deliver superior linearity in the output stage throughout the sonic range from musical details to robust current. The technique of driving multiple amplifier devices in parallel to secure robust current has solved the problem of muddiness in sound caused by uneven performance among the devices. And to achieve musical expression filled with the delicate nuances of sound.
High-gain amp construction:
The amplifier circuitry has been changed from the conventional two-stage configuration to a high-gain power amp in a single-stage configuration for a more direct signal path. A highly pure sound has been made possible by reducing the number of devices through which audio signals pass and shortening signal paths to an absolute minimum. The protection circuitry for the power amp output stage has also been considerably improved.
