The "Octave" is a continue development of the Nos Mini Dac. Besides the different dimensions of the housing, changes have been made in the power supply and the number of dacs used.

The "Octave" is not using a wall adapter. A separate heavy filtered 15 VA powersupply is used and switchable for both 115V AC or 230 V AC. The power from the toroidal transformer will be rectified in the dac and smoothed by 26 capacitors with an equivalent capacity of 12.000uF.

For each channel 4 extremely fast industrial dacs are used and having their own voltage regulators. This approach will improve channel separation, avoiding mutual influencing between both channels and improves noise figures.


The sound of this dac let you forget that you are listening to a digital source
