The newest PowerDAC for the Head-fi universe is released!
It is pretty much the same device as PDv2, however, now PowerDAC can work with unbalanced headphones as well. HPToy iOS/Android app was modified to get the switch for 3 output modes:
1) Balanced - the same as PDv2 balanced 2.5mm TRRS up to 600mW/channel output2) Unbalanced - you can use that mode with E1DA 2.5/3.5mm adapter to drive your unbalanced headphones, however, power in that mode is lower vs Balanced mode
3) Unbalanced Boost - the same as Unbalanced with full 600mW power but with some crossfeed effect. This is the price for the versatility of a single 2.5mm TRRS output
Also, PDv2.1 got the new USB audio bridge CT7601 Comtrue, instead of Cmedia which was far from ideal.
Soft-start Function
PDv2.1 has a soft-start function to avoid high inrush current, in fact, PDv2 may work with any Android phone without Y-splitter, if you wish to use such a power-hungry device with your phone.
Compressor/Limiter
This function really useful for an open back planars to "compensate" ambient noise. And limiter keeps sound distortion-free at high volumes, also you can see the output clipping indication in the app e) Preset manager allows to save/load presets and export/import(email/skype/www etc) as well to share PowerDAC settings between users f)
Intuitive Controllable Filters
7 parametric EQs, left/right gestures control frequency, up/down gain, zoom in/out Q-factor. Also available LPF/HPF and APF for phase alignment and text form Biquad control just in case. Default standard configuration: DAC+2.5/3.5 Adapter+Type B to A Cable
