recently switched to I2S hooked up to my Hibiki SDS--all good so far apart from the occasional popping/crackling noise which i'm still trying to get to the bottom of. I'm doubtful it's my HDMI cable and I suspect it's something to do with either the power supply I use on the QU02, or simply the internal clock inside the Hibiki SDS which occasionally does 'cut out' for a second or two when using coax (this doesn't occur on I2S, but there's also no popping/crackling on coax). i'm tempted to get the fiio pl50 to act as a linear power supply for the QU02, but I'm also doubtful that would make any change in the audio quality itself--moreso, just trying to troubleshoot on what's causing the popping. n.b. this only seems to happen on my Hibiki, not my Hugo TT.
also, while the SDS says it can support 768khz via I2S, anything above 384khz via my QU02 seems to generate an awful distorted noise. there are pins at the bottom of the QU02 in regards to the I2S output as theres no universal 'interpretation', it's possible that I might not have the correct combination, but after messing around with it I couldn't find the 'right' combination and just resorted to leaving it on 384khz and all the pins switched to 'on'.
maybe that's why!

maybe that's why!
