Ooberpad brings you Denon PMA-2500NE - Integrated Amp with USB-DAC for High-res Audio. 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.

Benefits of Denon PMA-2500NE Integrated Amplifier with DAC mode: 

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.

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, Denon has continued to focus on amplification performed by one pair of devices. 

High-speed thermal feedback circuitry

In addition to the UHC-MOS of the power amp and temperature compensation transistors, the PMA-2500NE incorporates transistors in the driver stage of the power amp that have been thermally bound to a radiator (copper plate). Since all devices related to idling current have been thermally bound, idling current is now more stable, giving greater clarity and stability to the sound.

Robust power supply circuitry

The PMA-2500NE is equipped with two transformers that have been mounted facing opposite directions in a leakage cancelling (LC) mount system to cancel mutual influences of magnetic flux, a source of noise, leaking from the transformers. Denon’s custom-designed, large-capacity electrolytic capacitors have been used for rectification, and low-loss, low-noise, high-speed Schottky barrier diodes have been used in the rectifier circuitry. This ensures a sufficient supply of clean current. To achieve a “simple & straight” circuit configuration, the connection unit between the diode unit and the block capacitor has been removed to drastically shorten the current supply line to the power amp. Extremely thick OFC wiring material has been used for the power line to reduce impedance.

6-block chassis configuration

The PMA-2500NE’s chassis is configured of six independent blocks that house the phono equalizer and input circuitry, volume control circuitry, USB-DAC circuitry, amplification circuitry, power section, and the control section. The chassis constructed with 1.6mm thick steel plates protects the signal circuits from external vibration and eliminates the adverse effects of mutual interference among the circuits.

The PMA-2500NE’s speaker terminals are gold plated to prevent corrosion over time and achieve reliable, long-term connections. Thick spades and banana plugs are also supported.
