What the Denon PMA-2500NE is about?

Denon is one of the few audio companies that has maintained an active commitment to developing Hi-Fi components and collecting, refining, and passing down Hi-Fi audio innovations. The 2500NE series is a product of the combined efforts of Denon’s seasoned engineers and its bright new engineers, who have taken on the mantle of developing the company’s signature technologies and building on the company’s decades-long legacy of audio excellence. 

The PMA-2500NE also offers superior performance compared to Denon’s PMA-2000 series. The PMA-2500NE is an absolute technological marvel, boasting cutting-edge connectivity in addition to premium build quality and innovative Denon technologies. The PMA’s rear USB-B input and built-in high-quality D/A converter allow it to flawlessly play high-resolution files from a computer, including those up to 384kHz/32bit and DSD up to 11.2MHz. The PMA has an Analog Mode that, when activated, disables the digital input circuitry and the low-noise display, allowing for pristine audio reproduction from analog sources.

Features of the Denon PMA-2500NE

UHC-MOS Single Push-Pull Circuit Technology for Optimizing Power and Miniaturization The Denon PMA-2500NE uses Ultra High Current MOS (UHC-MOS) FETs, which can generate a lot of current in a single push-pull arrangement and hence provide improved linearity in the output stage across the whole tonal spectrum, from subtle musical nuances to powerful current. Sound muddiness caused by uneven performance among devices has been resolved thanks to the method of driving numerous amplifier devices in parallel to secure robust current. 

Denon has persisted in concentrating on monoaural amplification as the means to generate musical expression full of nuanced tonalities. With its high-voltage, high-capacity UHC-MOS FETs, the PMA-2500NE is a formidable piece of equipment (peak current of 210A). Furthermore, the UHC-enhanced MOS’s acoustic properties may be consistently brought out thanks to the Dual FET + cascade bootstrap connection’s capacity to provide a steady voltage for the device while also enhancing temperature stability.

High-Quality AL32 Processing Plus, Accepting Inputs up to 384 kHz at 32-Bit PCM The PMA-2500NE uses Advanced AL32 Processing Plus, the most recent iteration of Denon’s analog waveform reproduction technology, for digital input. This technology incorporates novel data interpolation methods and facilitates the input of high-resolution 384 kHz/32-bit PCM signals. In order to create a smooth waveform that closely resembles the original signal, these algorithms interpolate points that should occur before and after the points in enormous volumes of data. Playback sound is extremely detailed, free of interference, precisely localized, vividly expressive in the lower range, and exquisitely authentic to the original sound by meticulously restoring data that was lost during digital recording. The PMA-2500NE accepts digital input, and after being processed by the Advanced AL32 Processing Plus, outputs high-quality analog signals to the subsequent stage’s amp block.

Specifications of PMA-2500NE

Minimizing undesired vibration through direct mechanical ground construction Central to the PMA-2500NE is the power section, which is supported by a sub-chassis made of three layers of 1.6mm thick steel plates. This construction’s well-balanced bulk, coupled with the heat sinks on both sides, makes it perfectly suited to preventing vibrations from degrading the audio quality. High-density felt cushions affixed to the bottom of the feet further absorb vibration, and the feet themselves are composed of highly durable, solid Bulk Molding Compound (BMC) to handle the weight of the power transformer, heat sinks, and chassis.

Six-cylinder engine, six-block chassis The PMA-2500NE’s chassis is split up into six different sections: the phono equalizer and input section, the volume control section, the USB-DAC section, the amplifier section, the power section, and the control section. The signal circuitry is shielded from external vibration and mutual interference thanks to the chassis’s 1.6mm thick steel plates.

USB digital audio converter that can play at 384kHz/32bit PCM and 11.2MHz DSD. The PMA-2500NE can take in high-resolution audio streams over USB, including 11.2-MHz DSD and 384-kHz/32-bit PCM. ASIO native playback and DSD Audio over PCM Frames (DoP) with Wasabi or Kernelstreaming are two examples of how DSD can be sent. A jitter-free transfer can be achieved by the use of asynchronous transfer, as the PMA-2500NE’s master clock regulates the process rather than a computer’s. With the same 384 kilohertz/32-bit DAC PCM1795 found in the DCD-2500NE, the PMA-2500NE is able to produce high-quality audio with minimal artifacts.

Reliable circuitry for the power supply The PMA-2500NE’s two transformers are installed in a leakage canceling (LC) mount system so that their magnetic fluxes, a potential source of noise, are canceled out by one another. Denon’s high-quality, large-capacity electrolytic capacitors were employed in the rectifier circuits, together with low-loss, low-noise, high-speed Schottky barrier diodes. As a result, you may rest easy knowing that you’ll have plenty of clean electricity to use. The connecting unit between the diode unit and the block capacitor has been eliminated to obtain a “simple & straight” circuit architecture and significantly reduce the length of the current supply line to the power amplifier. With the goal of lowering the power line’s impedance, an extremely thick OFC wiring material has been adopted.

Conclusion

The Denon PMA 2500 is a good-to-go product for you and definitely a good investment. It is designed for you in such a way as to meet all your needs!
