Play high-resolution audio files

Connect your computer directly via the asynchronous USB port. The integrated ESS ES9016S D/A converter processes signals itself with top resolution types such as Quad DSD with up to 11.2 megahertz, and PCM files in WAV or FLAC format with up to 384 kilohertz and 32 bit.

No chance for troublemakers

The three-part chassis effectively shields the power supply, pre-amplifiers and power amplifiers and avoids mutual interference. A fully symmetrical pre-amplifier circuit and symmetrical Neutrik XLR ports achieve the best possible signal-to-noise ratio. XLR connections are standard in the area of studio engineering and much less prone to any kind of interference.

Efficient amplification

The highly-efficient MOSFET Class D amplifier supplies 90 watts per channel and facilitates extremely dynamic, detailed and precise sound reproduction.

Perfect for lovers of vinyl

Connect your record player very easily to the phono input using an MM system and enjoy your vinyl collection in the best quality.

Symmetrical connection

The A- 70DA is equipped with a Neutrik 3-pin XLR input. Thanks to the fully balanced preamplifier XLR connection guarantees maximum sound quality, for example in interaction with the network players N-70A or the Universal Player BDP-LX88.
