Just keep in mind, DO NOT use easy to drive phone directly into EXTASY, get a volume controller or impedance adapter else it will turn your headphone into a speaker and there are noticeable hiss with sensitive phone.
I like the sound signature of EXTASY a little better but uDAC (RCA out) is more versatile for easy to drive phone with build in volume control.

Yes that is true....
It does have 'hiss' with certain headphones and it IS Extremely powerful.
Don't use IEMS or EAR BUDs with this DAC.
And ALWAYS start out with the volume turned DOWN before playing any music!!!! VERY IMPORTANT!!!
If you could also list the headphones it has hiss with I'd be very appreciative of that.
I will then do experiments to eliminate that hiss on future designs.
I have really only designed the DAC-EXTASY to work with the top full sized headphones....
I wasn't really thinking about it being used with anything but the Grado or Sennheiser HD series headphones.
I mean if you're going to spend $499 to $1500 on headphones, you for sure will need a good source to drive them ???
The DAC EXTASY can NOT and SHOULD not be used with any IEMs or ear bud style headphones.
NEVER USE THE DAC-EXTASY with EAR BUD or IEM style headphones....
I was VERY surprised by the POWER the Wolfon chip had....
It took me completely by surprise.
It goes SO loud on my headphones that no additional amplifier is necessary.
And for sure WILL NOT WORK WITH EAR BUD or IEMS!
Don't even try to use it with them.
It is ONLY meant for FULL SIZED headphones and real expensive ones at that...
I am thinking of making a 'patch cable' or maybe even putting a switch in it for different types of headphones....
However it is and was NEVER my intention to make this DAC compete against the uDAC or any other DAC for that matter.
It is a different kind of DAC.
Not multi-purpose.
It only has ONE purpose....
I really should have priced the DAC-E much more carefully....
It isn't really meant for the 'noob'.. no insults intended for all you 'noobies'... I was a 'noob' once too...
I don't want anyone trying the DAC-E with the wrong type of headphones or damaging their ears by playing music too loud.
That was NEVER my intention.
And I now realize that the DAC-E was in reach of the 'noobie' and the 'noobie' budget... and that was a mistake...
It then of course made it seem like an 'budget' or intro DAC....
I never saw that happening... but I see the flaws in my logic now...
I have fixed that flaw for now.
I find the dynamics of the whole audio scene quite fasinating....
