Baffled and Frustrated: Streaming/DAC Sound Issues


Hoping to find some guidance here regarding a significant noise issue. Running Quboz through Roon. Relevant Gear is an Auralic Aries G2.1 > Morrow USB cable >Aavik D280 DAC > Wywires Platinum RCA >Anthem STR.  

Previously had some issues with the Aries but that’s hammered out and sounding great.  Now, when running many songs through the DAC, I’m hearing terrible “crunching” distortion.  There’s very little consistency in the problem (loud Pink Floyd sounds great, loud Motley Crue sounds like garbage) except most hard rock/metal, which i started putting on per Morrow Audio’s recommendation for burning in their USB cable, is always terrible.  Volume is irrelevant, I’m getting the noise at sub-30db. The 4 DAC settings: upsampling/ non upsampling/fast/slow don’t change anything. USB cable isn’t likely the problem, it sounds great from streamer to amp without the DAC.   I’m running out of settings to change around.  Anyone have an educated guess or experience with either the output settings from the Aries or D280 setup that can provide any guidance?  Dealer wasn’t very helpful.

 

Thanks much,

Peter

Use the HDD or USB drive to play stored files so you can isolate the problem to only streaming/ROON.

If problem persists change USB cable.

Still persists, it's the DAC.

I have distortion similar to @designsfx but with single ended  connections.  It vanishes if I lower the volume at the streamer and raise it via the pre.  It's an over driven pre situation.  

The  Aavik D280 puts out 4.5 V rms = 6.363 peak.  

@clearthinker Why?

That was no help at all and kind of douchey. 

Junk this digital crap and get some LPs

or else become Albert Einstein
