The state-of-the-art HDVA 600 headphone amplifier allows you to fully

exploit the potential of your high-end headphones. The HDVA 600’s consistently symmetrical signal processing and extremely low harmonic distortion ensures an unadulterated and perfect music enjoyment.

The HDVA 600’s output circuitry is designed for use with up to four

dynamic headphones. Consistent wiring and the use of XLR-4 sockets

ensures an excellent channel separation.

You can connect digital audio sources such as CD, DVD and Blu-Rayplayers

and analog audio sources such as as tuners, open reel machines and turntables with a corresponding preamplifier to the HDVA 600. Digital sources

are connected via their analog outputs. The input selection rotary switch

allows you to switch between the connected audio sources.

The headphone amplifier and the Sennheiser HD 800, HD 700 and HD 650

high-end headphones are optimally matched with regard to technology,

design and performance characteristics and fulfil the demands of the most

discerning audiophile.
