Ground Zero Reference Pure

The Reference line stands for selected high-end products with outstanding sound quality. The GZPA Reference PURE is an advanced 2-channel amplifier with a dual mono direct signal layout. Due to the separated channels and direct signal paths, it delivers excellent sound quality. The direct signal paths could be realized by omitting all sound-altering components, potentiometers, and switches.
