I2S, PLL and USB

Hey guys,

Just getting good enough gear now to wonder about this stuff. My streamer can output I2S to my DAC. But I have to turn off PLL or the DAC tries to lock and ends up missing the first 1-2 seconds of the music. Turning PLL off and it plays fine. Is I2S worth it or should I use USB? The streamer is quiet on USB as well

Thanks
