NVA A70 MKIII Monoblock Power Amplifiers


Designed to be used with NVA passive pre-amplifiers, the A70 rivals 'high end' amplifiers at many times the price. This exceptional value is achieved through our minimalist design ethos and modern distribution model.


For operational stability this amplifier must only be used with NVA low capacitance speaker cable. Use of other makes of speaker cable will invalidate our warranty. For optimum sound quality, we recommend use of our low capacitance interconnect cables.
