After years devoted mainly to home theater, Onkyo makes a notable comeback to the world of stereo high-fidelity with the ICON P-80. This network preamplifier crystallizes nearly eight decades of Japanese acoustic expertise, integrating cutting-edge technologies like the patented DIDRC circuit and Dirac Live room correction. Priced at $1,999, the P-80 is part of the new Icon series that symbolizes the rebirth of a brand founded in 1946 and now revitalized under the aegis of Premium Audio Company.
A metal build that exudes solidity
The P-80 adopts a construction in three distinct parts: two aluminum side panels and a steel top panel. This tripartite structure significantly increases overall rigidity and improves resistance to vibrations. The “oval” chassis, characterized by oval pressure lines on its underside, effectively disperses unwanted vibrations. The 5 mm thick aluminum front panel not only contributes to the device’s clean, modern aesthetics, but also plays a crucial role in suppressing unwanted resonances.
The extruded aluminum heatsink performs a dual function: heat dissipation and vibration suppression. This fanless design ensures completely silent operation, an essential element for preserving the purity of the audio signal. Gold-plated terminals, audiophile-grade capacitors, and PCBs with 70-micron traces demonstrate meticulous attention to the smallest details. Measuring 43.5 cm wide, 13.5 cm high, and 35.5 cm deep, and weighing 12 kg, the P-80 has a commanding presence without appearing bulky.
The DIDRC circuit: a revolutionary technology against distortion
DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) is a revolutionary circuit that handles playback frequencies up to the MHz range and delivers up to 1000 V instantaneously—that is, in 1 µs, or one millionth of a second. This patented Onkyo technology tackles a commonly overlooked problem: distortions in ultra-high frequencies, far beyond the human audible range.
While conventional amplifiers can physically produce frequencies in the 100 kHz to 1 MHz range, distortion at these frequencies is extremely problematic. These distortions, though not directly audible, generate beating that affects the character and atmosphere of the original sound within the audible range. DIDRC eliminates these interferences by maintaining exceptional linearity even at extreme frequencies.
In the P-80, the DIDRC circuit is strategically implemented in two critical sections: the analog filter of the digital-to-analog converter and the phono stage circuits. This dual implementation enables a natural and emotional sound reproduction, whether from digital sources like streaming services or analog sources like vinyl records. Onkyo’s engineers have particularly refined this technology so that digital sources sound as natural as analog recordings, bridging the traditional gap between these two worlds.
A state-of-the-art digital-to-analog converter
At the heart of the P-80’s digital section lies AKM’s AK4452 DAC from Asahi Kasei Microdevices, a 32-bit converter capable of handling signals up to 768 kHz. This next-generation DAC incorporates AKM’s VELVET SOUND architecture, widely adopted by high-end audio manufacturers. This technology achieves fine sonic detail thanks to its low-distortion architecture. The AK4452 delivers remarkable performance with a 115 dB signal-to-noise ratio and a total harmonic distortion plus noise (THD+N) of -107 dB.
The chip natively supports PCM up to 768 kHz as well as DSD (Direct Stream Digital), offering full compatibility with modern high-resolution audio sources. The Velvet Sound architecture was specifically designed to support the high-resolution audio market and achieves the industry’s lowest distortion. The DAC’s built-in 32-bit digital filtering helps preserve signal integrity throughout the conversion chain.
The P-80 fully leverages this premium DAC by pairing it with carefully optimized analog circuits. The physical separation of digital and analog circuits, each with its own power supply, minimizes interference and preserves the purity of the converted signal.
Dirac Live: mastering your listening space
The P-80 integrates the Dirac Live Room Correction Suite Stereo, a feature usually reserved for very high-end equipment. Dirac Live analyzes how sound behaves in your space, automatically adjusting your speakers to eliminate distortions, correct timing issues, and balance the overall sound. The included base version corrects frequency response from 500 Hz to 20 kHz, sufficient to effectively address the most common acoustic problems.
Unlike basic equalization systems that mainly flatten frequency response, Dirac Live corrects both frequency response and impulse response. This dual correction ensures not only optimal tonal balance but also precise reproduction of transients, without smearing or delay. The system can create multiple correction profiles, allowing sound reproduction to be tailored to the musical genre or listening preferences.
For users who want to go further, Onkyo offers optional upgrades to the full version of Dirac Live, as well as Dirac Live Bass Control and Dirac Live Active Room Treatment (ART). The P-80 is thus one of the first products outside Storm Audio home theater processors to promise compatibility with Dirac Live ART. These extensions enable even more precise acoustic control, particularly in low-frequency management with the two independent subwoofer outputs.
A phono stage designed for vinyl
The P-80’s phono stage benefits from a circuit completely independent from other sections, ensuring perfect isolation from interference. Compatible with moving magnet (MM) and moving coil (MC) cartridges, it adapts to the most demanding setups. The fully discrete MC circuit accurately reproduces the delicate signal of moving coil cartridges without introducing distortion.
The implementation of the DIDRC circuit in the phono stage represents a significant advancement for vinyl playback. This technology, initially developed to improve digital sources, finds a particularly relevant application here by preserving the natural musicality of analog recordings while eliminating parasitic distortions. Dedicated phono terminals, without superfluous switching circuits, ensure an optimal signal path with a minimal number of contacts.
Modern, versatile connectivity
The P-80 offers exceptionally rich connectivity to meet all needs. On the analog side, there are three pairs of line-level RCA inputs and the aforementioned MM/MC phono input. Outputs include one pair of unbalanced RCA pre-outs and one balanced XLR pair, allowing optimal connection to any type of power amplifier. Two independent subwoofer outputs enable sophisticated bass management configurations.
The digital section includes an HDMI ARC input for connection to modern TVs, a coaxial input, and an optical input for traditional digital audio sources. The USB-A port enables direct playback from storage devices, providing a convenient solution for accessing locally stored music libraries. A 6.3 mm headphone jack output rounds things out, allowing for quality private listening.
Network connectivity is one of the P-80’s strong suits. Built-in Wi-Fi and an Ethernet port ensure a stable connection for streaming. Bluetooth with support for SBC, aptX, and aptX HD codecs offers a convenient wireless solution for mobile devices while preserving superior audio quality thanks to high-definition codecs.
A complete streaming platform
The P-80 integrates seamlessly into the modern music streaming ecosystem. Native services include Spotify Connect, TIDAL Connect, Amazon Music, and Qobuz Connect, allowing direct control from their respective apps. This native integration ensures optimal streaming quality without additional compression. TuneIn provides access to thousands of Internet radio stations around the world.
Roon Ready certification places the P-80 among devices compatible with this sophisticated music management platform, particularly appreciated by audiophiles for its metadata handling and refined user interface. Apple AirPlay 2 compatibility enables seamless integration into the Apple ecosystem, with multiroom support. Chromecast built-in offers a similar solution for Android users and services compatible with Google Cast.
The Onkyo Controller mobile app centralizes control of all these features. From the listening position, the user can adjust settings, browse content, and switch between sources without leaving their seat. This modern approach to control aligns with the P-80’s philosophy: combining audiophile tradition with contemporary convenience.
Fidelity IQ: intelligent loudness
Beyond traditional tone control with separate bass (100 Hz ± 10 dB) and treble (10 kHz ± 10 dB) adjustments, the P-80 includes the Fidelity IQ function. When Fidelity IQ is enabled, the system automatically provides optimal audio playback at any volume in conjunction with the master volume. This feature goes beyond simple traditional loudness compensation.
Onkyo’s sound engineers adjust the frequency response to deliver the most emotional sound possible, regardless of musical genre. Parameters are generated for the listening environment using the setup microphone during initial calibration. This function operates independently of the tone control and can be used in conjunction with it, offering maximum flexibility in tailoring sound to personal preferences and listening conditions.
