E1DA Power Dac v2.1

General Information

PowerDAC v2.1

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.

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.

Hi, thx for the review :)
I had the original version, and loved that. I am thinking of getting the Arya Stealth. Can the 2.1 version drive the Arya Stealth well?

Have had the v2.1 for a few years now and used it on the last 4 or 5 Mac OS versions. It works absolutely fine on Mac OS.
Was on a USB-A Mac and now on a USB-C Mac. All good
