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.
