This is an old thread, but for future readers who might stumble onto it, I have evaluated the DHLabs coax against some other wires with a later generation Node and found a huge difference in sound performance. @ianrmack, I ended up buying a used Chord Signature Super ARAY that cost as much as the Node. I have no regrets, and I am currently using it to connect my Node 130 to a Chord Qutest DAC.
Here is the result of my coax cable testing:
Fwiw, the Chord QuteHD DAC used in this analysis had an upgraded MCRU power supply with a very good power cable and was surprisingly close to the Qutest in performance.
