Ground Zero GZHA MINI FIVE

GZHA mini-amplifiers are representign latest D-class technology that is also used in OEM-amplifiers. Main difference to traditional D-class is much better sound quality throughout whole bandwith. It is impossible to say in a blind test that are you listening to good AB-class amp or GZHA mini-amplifier.
