When I purchased my Denafrips Pontus II DAC, I was informed by Alvin at Vinshine Audio that using both the XLR and RCA outputs simultaneously would result in a degradation of performance for the DAC. I also wanted to connect my DAC to both my integrated amp and headphone amp. Alvin then sent me a design for a custom cable that would solve this problem. The cable connected to the XLR outputs from the DAC and split off into two separate RCA connections to each of the amplifiers. I sent this design to Morrow Audio and they built the cable for me which has performed flawlessly. The only downside is having to use RCA instead of XLR to my integrated amp which I use way more than my headphone amp.
