Headphones Amp with D/A Converter


The Evo HPDAC Two is a high performance, discrete components, remote controlled headphones amplifier with builtin DAC. It encompasses a high performance USB DAC capable of handling PCM up to 384/32 and DSD up to 25- 6x. The Evo HPDAC has a low impedance headphones output on 6.35mm socket, to accomodate high quality headphones. Digital inputs include USB and coax. Two analog inputs complete the input provision. The high output voltage is optimal for driving low sensitivity headphones. High power capability allows for up to 1W p.c. on 32 Ohms hradphones. The remote control allows for handling volume, balance, mute and input selection.
