I am trying to placen what hw to use for a perhaps future vlumio based music player. As my budget are pretty low I am planning to go with a Raspberry Pi and after reading up some I concluded I wanted this DAC: ebay.com/itm/141021544210 (XMOS ES9023 Asynchronous DAC Decoder USB to Optical Coaxial 384K 32Bit Weiliang).
I also see the flexibility to be able to keep the DAC (as it is USB based and not I2S based) if I upgraded the Raspberry Pi to another solution in the future.
But now I read at list-i2s-dacs-for-raspberry-t1103.html :
Will a I2S based DAC really give better sound then the USB DAC linked above?
Any other suggestions?
