Presenting the all new m900

Compact, Portable Headphone Amp / DAC / Monitor Controller

What if we took the sonic DNA from our flagship m920 headphone amp/DAC and made a truly portable version? What if we made it bus powered so you could simply plug it into your laptop and go? What if we put TOSLINK and S/PDIF inputs on it that handled 24-bit/192kHz audio and also included asynchronous USB to handle rates up to 384kHz PCM as well as DSD64, DSD128 and DSD256?

And while we’re at it, added a pair of outputs for connecting to your stereo monitoring system?

Well, that is exactly what we did: introducing the new m900: a world-class headphone amp/DAC/monitor controller for pro and consumer use with a street price of only $499 (US). Made in the USA and backed by a 5-year transferrable warranty.
