Denon PMA-1700NE Black Hi-Fi Integrated Amplifier

Reference-Class Integrated Amplifier with USB-DAC

The Denon PMA-1700NE integrated amplifier is a two-channel, 70-watt-per-channel powerhouse engineered for listeners who want a single component to anchor a serious hi-fi system. Built around Denon's new UHC-MOS single push-pull power amplifier circuit, it delivers 70 W per channel into 8 ohms and 140 W per channel into 4 ohms, giving it the current reserves to control a wide range of loudspeakers. This integrated amplifier is the right choice for audiophiles who want a single component that combines a high-current analog amplifier, a high-resolution USB-DAC, and a full-featured MM/MC phono stage without resorting to separates.

What Sets This Amplifier Apart

At the heart of the unit sits Denon's Advanced AL32 Processing Plus, a waveform reconstruction algorithm that interpolates digital audio up to 384 kHz/32-bit to restore information lost during recording. The asynchronous USB-B input uses a new XMOS XU210-256-TQ128 chipset paired with a Burr Brown PCM1795 DAC and full galvanic isolation, suppressing jitter before the signal reaches the analog stage. A Source Direct function bypasses tone controls for the purest signal path, while the Analog Mode button on the front panel disables all digital circuitry when listening purely to analog sources.

Power Amplifier Performance — Drive Any Speaker

The power stage uses Denon's new UHC-MOS single push-pull topology with a dual El-core power transformer, providing high current delivery and stable operation into low-impedance loads. Total harmonic distortion is rated at just 0.01% at -3 dB rated output into 8 ohms at 1 kHz, and frequency response extends from 5 Hz to 100 kHz for full-range musical reproduction.

• Rated Output Power: 70 W + 70 W (8 ohms, 20 Hz-20 kHz, THD 0.07%) — comfortable headroom for most listening rooms
• Dynamic Power: 140 W + 140 W (4 ohms, 1 kHz, THD 0.7%) — extra current for demanding speaker loads
• Speaker Impedance: A or B: 4-16 ohms / A+B: 8-16 ohms — supports bi-wiring with two independent speaker pairs on gold-plated terminals

USB-DAC and Digital Inputs — High-Resolution Playback

The integrated DAC handles every modern high-resolution format, from CD-quality redbook to native DSD, with full isolation between the digital and analog grounds to keep noise out of the signal path.

• USB-B Input: PCM up to 384 kHz/32-bit, DSD up to 11.2 MHz (DoP) via asynchronous XMOS — Roon Tested for plug-and-play computer audio
• Optical / Coaxial Inputs: 2 optical + 1 coaxial (192 kHz/24-bit) — for set-top boxes, CD players, or network streamers
• DAC Chip: Burr Brown PCM1795 with Advanced AL32 Processing Plus for analog waveform reconstruction

MM/MC Phono Stage and Analog Connectivity

A discrete phono equalizer supports both moving-magnet and moving-coil cartridges, with a front-panel switch to change cartridge type without rewiring. Signal-to-noise ratio reaches 107 dB on the CD/line inputs and 89 dB on the MM phono input, ensuring quiet backgrounds even with low-output MC cartridges.

• Phono Input: MM: 2.5 mV / 47 kohm, MC: 200 µV — switchable from the front panel, no rewiring needed
• Analog Line Inputs: 4 RCA inputs (Phono / CD / AUX / Recorder) plus 1 REC output
• Headphone Output: 1/4" (6.35 mm) front-panel jack — driven by the main power amplifier stage for full-bodied private listening

Who Should Choose This Integrated Amplifier

The Denon PMA-1700NE is the right choice for serious hi-fi listeners who want a single, full-featured integrated amplifier that can anchor a vinyl-and-digital system without compromise. It suits owners of low-sensitivity or 4-ohm floorstanding speakers who need the high-current reserves of a UHC-MOS push-pull stage, as well as computer-audio enthusiasts who want to bypass their sound card and feed a USB-DAC capable of native DSD and 384 kHz PCM. Vinyl collectors running either MM or MC cartridges will appreciate the switchable phono stage, while the included system remote (with CD player control) makes it a natural partner for a Denon CD transport such as the DCD-1600NE.
