When it comes to valve amplifiers, power outputs of around 30W to 50W tend to be the norm. In some instances, this figure might rise to around the 100W mark.
But Audio Research’s new Reference 330M monoblock power amp takes this to a whole new level with, you probably guessed, a mighty 330W of power per amplifier. That’s more than double the 160W of the company’s previous flagship, the Reference 160M MkII.
