EWA Q-20-P Pre-Amp & Headphone Amp

EWA Q-20-P Pre-Amp & Headphone Amp

Do not let their size fool you, these are high end amplifiers designed by the same man who created the world's largest ever Single Ended Class A amplifiers. Sharing that heritage, Q-amplifiers are perfect for efficient loudspeakers, or A/V systems, offices and bedrooms due to their tiny form factor. (179mm X 76mm X 195mm)


Featuring inbuilt high performance MM/MC phono stage and powerful, dynamic headphone amplifier, a sophisticated linear power supply, Q-amps are the equal of most high end full size amplifiers. It's partly down to that power supply...


The PCB tracking has been designed to shield all signals and to keep the track mass identical between the channels. This reduces timing and phase errors to nothing, making Q-20-P a truly sophisticated pre- and headphone amplifier. 

Captive mains lead fitted as standard. 3.5mm headphone jack.
