Constant Current Drive
Groove's Constant Current Drive output stage is a truly revolutionary approach to dealing with the wide impedance variations of headphones available on the market today. With Constant Current Drive topology, Groove's output stage's voltage is dynamically "molded" to the impedance variations of the connected headphones, thereby smoothing out frequency response non-linearity that occurs with traditional headphone outputs.
Quad Sum DAC
Groove also features a Quad Sum DAC design which employs four digital-to-analog converters per channel to achieve the highest dynamic range and lowest distortion (THD+N) of any device in its class.
