The Reference 330M is the finest amplifier ever created by Audio Research, with the ability to control any loudspeaker with a vice-like grip and startling dynamic life. It is the culmination of everything we have learned over 50+ years.

It is a statement that music is king, always ready to sweep you away. Infusing new technology and circuits with the finest vacuum-tube architecture, the 330M elevates music reproduction to the highest plateau with an all-tube signal path.

Price is for a pair of 330M Monoblock amplifiers.

This is our heritage, the legacy created by our founder, William Zane Johnson.

The finest amplifier ever created by Audio Research

From its ECC83 input to its KT170 output, with tube regulation in the power supply, the 330M proves that you can enjoy the ease of high power along with a delicacy and purity usually associated with low-power amplifiers. Tonal saturation and density accompany a specificity of recording space beyond anything we have built.

Liquidity and artistry abound, yet with blade-like edge precision when called for. Extension at both frequency extremes is state of the art even for solid state amplification. Statement-level loudspeakers capable of meaningful infrasonic bass output will be fully commanded down through their lowest octave without a hint of retreat. Stones unturned: None.

Features

• The 330M was designed to provide ultimate performance without worry.

• Auto bias assures rock-steady consistency, minute-by-minute, day in and day out.

Who is this for?

Who is this for?

The Reference 330M is designed for the discerning audiophile who has already assembled a high-resolution system and recognizes that their speakers deserve more power and finesse than their current amplification can deliver. If you're driving demanding loudspeakers—whether they're large-scale floor-standers, electrostatics, or planar magnetics—and you've noticed compression during complex passages or a lack of that final degree of control and transparency, these monoblocks will transform what you're hearing. This is the amplifier for listeners who know the difference between adequate sound and true sonic excellence.

Your listening room should be medium to large, ideally treating spaces from 300 to 600 square feet where you have the physical distance to let your speakers breathe and the 330Ms to flex their considerable muscle. These monoblocks thrive in dedicated listening environments where acoustics have been considered and where you've invested in proper speaker placement. If your room is smaller or your speakers are efficient designs above 92dB sensitivity, you'll likely find more synergy with Audio Research's lower-powered options—the Reference 330M's 350 watts per channel is purposeful power for speakers that demand it.

In your system, each 330M takes its place as a dedicated monoblock beside or behind your speakers, driven by a Reference-level preamplifier that shares their commitment to vanishingly low distortion and complete signal integrity. They represent the foundation of a cost-no-object two-channel system, the kind where your source components, cabling, and room treatments are all operating at a commensurate level. If you're at the stage where you're chasing that last percentage of realism and you have speakers capable of revealing it, the Reference 330Ms will take you there.
