Ultra High-Current MOS Single-Push-Pull Power Amplifier, Three Power Supplies, and High-Res Quad DAC Fuel PMA-A110: Denon Integrated Amplifier Also Features Gorgeous Looks
Fueled by a patented Advanced Ultra High Current (UHC) MOS single-push-pull circuit power amplifier, a 32-bit/384kHz Quad DAC, and three independent power supplies, the Denon PMA-A110 integrated amplifier is pure luxury audiophile performance and a collectible component deserving of commemorating the Japanese company's 110th anniversary. Outfitted to handle high-resolution digital up to DSD 11.2MHz via the USB DAC input as well as vinyl via the built-in MM/MC phono preamplifier with CR-type equalizer and traditional sources by way of multiple optical and coaxial inputs, the 29-pound unit covers practically all bases – and looks incredible in any setting.
Outputting a conservatively rated 80Wpc into eight ohms (160Wpc into four), PMA-A110 provides huge current in a single push-pull configuration to drive speakers with ease and offer superb linearity in the output stage. For additional fidelity, the presence of Ultra AL32 Processing – Denon's cutting-edge analog waveform reproduction technology – utilizes data interpolation algorithms that should exist before and after the points in large quantities of data to achieve a smooth waveform that is close to that of the original signal. In addition, Ultra AL32 Processing touts processing bandwidth of 1.536MHz, leading to digital playback free of interference, accurately localized, and richly expressive in the lower range.
The four Burr-Brown PCM1795 DAC chips and accompanying architecture in PMA-A110 prove equally beneficial. To accurately synchronize digital circuits and the Quad DAC, PMA-A110's master clock adopts a dual low-phase noise oscillator that suppresses jitter and ensuring optimum conversion precision. Moreover, PMA-A110 employs a clock oscillator to dramatically reduce phase noise as well as two more clock oscillators, one for each sampling frequency (44.1kHz and 48kHz). The addition of a high-speed isolator circuit between the digital and analog sections further confirms PMA-A110's commitment to sonics.
Ditto the robust power-supply circuitry, complete with two transformers mounted facing opposite directions in a leakage-cancelling (LC) system to cancel mutual influences of magnetic flux. Denon's new, custom, large-capacity electrolytic capacitors handle rectification while low-loss, low-noise, high-speed Schottky barrier diodes can be found in the rectifier circuitry to enable a sufficient supply of clean current. Adhering to a simple and straight principle, the connection unit between the diode unit and block capacitor was removed to shorten the current supply line to the power amp.
And no, we haven't forgotten about PMA-A110's head-turning appearance. Adorned with an aluminum top panel, it boasts a well-balanced six-block chassis with direct mechanical ground construction to prevent interference, heat sinks on both sides, and solid aluminum feet that dampen vibrations. Recognizing the importance of touch and feel, the volume, balance, and tone controls all subscribe to a tactile analog sensibility and ultra-smooth operation. Just trying to keep your hands-off these gorgeous knobs will present a challenge.
Boxed with a certificate of authenticity signed by Denon's Head of Engineering, PMA-A110 also comes with a headphone output, Pure Analog Mode, TV-Auto Standby Mode, and gold-plated terminals. A five-year manufacturer warranty, remote control, and our 100% Music Direct Satisfaction Guarantee invite you to celebrate 110 years for years to come.
