Tcotruvo,
I have the 3rd generation node, and did A/B testing with my Denafrips Ponuts II DAC......absolutely no comparison; the Denafrips improves the sound on every single measurable I can think of. Also though the Denafrips Pontus II ($1,825 US) is twice the price of the Ares ($840 US)....it is worth every penny of the upgrade. The Pontus punches WAY above it's price
