Between a Node 2i and DAC: Does Coax cable quality really matter?

Yes better cable helps but the bigger difference for me was adding the iFi SPDIF iPurifier 2. Amazon carries it so risk free trial.

@rareace, the iFi does improve the SQ in several ways, music has more weight, wider deeper soundstage, more dynamic. I'm also using a Swagman Labs LPS.

What's the difference between  iPurifier2 and the first generation?

I have chord Qutest so jitter not much of issue.
I used iFi on older DAC and thought it was a subtle improvement.

may look at new coax...why not, right...?

@lowrider57  I’ve never tried the first generation. Only have the Purifier 2.

Without a LPS you don't get the full benefit of the iPurifier. I tried it both ways, the wall-wart had no balls.
