OP it may be easy to try the Denafrips Ares used. You should be able to hear a difference. Denafrips does not offer returns. You can pick one up used between $700 to $725 shipped and sell it in a day or 2 for the same price you paid. Not losing any money. The Pontus used you could lose or make a couple hundred depending on the deal you find if you choose to sell it.
I borrowed a Ares from a friend to see what all the hype was about when I was considering the Pontus. For a $800 dac I think the Ares is nice for the money. It has nice bass good soundstage maybe lacking in information but that could be why most move up the line. I owned the Quetest a while back and enjoyed the Ares more for its analog and musical presentation.
