E1DA PowerDAC V2.1

$89.99 USD

Headphone Amp PEQ DSP BLE DAC with 2.5/3.5 Output

    3 Output Modes
    New USB Audio Bridge
    Soft-start Function
    Intuitive Controllable Filters

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 output

2) 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.


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

Customer Reviews

Based on 2 reviews
Very impressive

Highly recommend this device. Can make an average set of headphones shine small adjustments to the bass/treble and loudness wet/dry controls. More in depth parametric eq is included as well with saved presets and you can create your own as well. Very impressive device well worth it.

Christopher Mosson
Faulty Product.

On the day it arrived the Bluetooth gave up and the audio port ceased to function. The fact that I've had to make a video proving the Sound and Bluetooth dose not work is an equivalent to showing that the water from a tap is not hot. It's impossible.

I've not had further correlation with the staff as.they seem unwilling to help!

Hello there. Thank you for the feedback.
The internal Bluetooth function is to connect to a phone's HPTOY APP. This E1DA device only works with the HPTOY APP.
Only when the device is connected to the HPTOY APP, could it work to adjust the settings e.g. volume, EQ and etc.
