High-end power amplifier, newly introduced by Audio Research, packs a substantial power punch.
Introducing the Audio Research Reference 330M: A High-End Tube Monoblock Amplifier
Twenty-five years from now, seventeen notable hi-fi and AV products will celebrate their silver jubilee. Among them is the Audio Research Reference 330M, a monoblock tube power amplifier that promises to redefine audio performance.
The Audio Research Reference 330M is a fully balanced pentode design, boasting an impressive power output of 330 watts per amplifier. Its output stage is powered by six KT170 valves, renowned for their high power and low distortion. The amplifier also incorporates one ECC83 and one 6H30 tube, and features automatic tube biasing to maintain consistent performance without manual adjustment.
The amplifier's design is as distinctive as its performance. The stainless-steel front panel is dominated by a "ghost meter"—a transparent, adjustable power meter that visually displays output in watts. Controls on the front include power on/off, meter lighting adjustment, meter on/off, and output-tube condition indicators via six LEDs aligned with the tube sockets. The tubes themselves are exposed behind the front panel without a protective cage, and the amplifier incorporates a ventilated U-shaped enclosure at the rear to house transformers and choke for efficient cooling and performance stability.
The Audio Research Reference 330M comes with both XLS and single-ended inputs, making it compatible with a wide range of audio sources. It also offers output taps for 4 ohms and 8 ohms, providing flexibility for various speaker configurations.
The Audio Research Reference 330M is more than just a high-power amplifier. It's a testament to the merging of classic tube sound quality with modern conveniences like auto-bias and visually engaging status indicators.
In the UK, a stereo pair of the Audio Research Reference 330M is expected to cost around £92,000. The amplifier was unveiled at the Bristol Hi-Fi Show 2025, alongside other products from companies such as Musical Fidelity, Rega, WiiM, and Quad.
Michell also made an appearance at the Bristol Hi-Fi Show 2025, unveiling its high-end Apollo phono stage and Muse power supply. These products are designed to preserve the integrity of the music for vinyl enthusiasts, ensuring a faithful reproduction of the original sound.
As we look forward to 2025, the Audio Research Reference 330M is poised to set a new standard in high-end audio. With its powerful performance, advanced monitoring of tube condition, and modern conveniences, it's an exciting addition to the world of hi-fi.
