I recently ordered a wireless audio kit (Raspberry Pi Zero + phatDAC) to extend my multiroom audio setup.
However after assembling the unit I’m a little bit dissapointed about the audio quality.
The sound I’m getting out of the device sounds somewhat too bassy and by far not as clear as the sound from my other multiroom clients (Raspberry Pi 1A, Raspberry Pi 1B+ and Synology NAS, each of them equipped with a usb audio adapter). It sounds like listening to loud party music through a shut door.
The software I used for the test was
Test 1: the latest max2play HifiBerry image (m2p_rpi3_hifiberry_235_wps.img) with the squeezelite player from https://www.max2play.com/en/max2play-image/
Test 2: the latest raspbian jessie image (2016-11-25-raspbian-jessie-lite) with the phatDAC installed according to your tutorial (https://learn.pimoroni.com/tutorial/phat/raspberry-pi-phat-dac-install) and playing music from the network using the squeezelite player / playing local music using the mpg321-player.
I tried the 3,5mm and the RCA output.
I connected a JBL Charge 2 speaker, a Medion Life P69053 speaker and a LG mini stereo system.
I tried the PhatDAC on the Pi Zero and on the Pi 1B+.
I also tried several AC Adapters
Does anyone have an idea what is wrong here?
Is this a hardware problem, a software problem or is the DAC supposed to sound ike this?
