This weird trick lowers DAC distortion

I was goofing around with a PCM1794A chip when the idea occurred to me to see what happened if I hit it with some freezer spray. Monitoring with the REW real-time analyser, I gave it a quick blast. The reported THD dropped a little. Another blast lowered it some more. I kept going. The chip got covered in ice crystals. At a temperature of about -25 °C (according to thermal camera), the THD was some 5 dB lower than the starting point.

 

The lesson here is clear. We need silent-running audiophile freezers with stylish looks and convenient cable inlets.

 

Or keep the DAC in the freezer?
