@[deleted]: finally I received the DAC+ from HifiBerry. Simply fix it on the RP2 into the GPIO 40 pins easily. Then uncomment the line of dacplus in the config.txt ...wow its sound is great...at least it is great against to its price

. Finally thanks you bro for your supports during last time.
I am discovering more by next step for the dsd dac that I am considering the s.ms.l m8 since it is $109.-
