If I understand correctly you're using the dual-3-pin-XLR outputs at the back? And you like the sound better than the single-ended headphone output in the front?

In my case I use the RCA outputs as the XLRs are needed for the active speakers. On the Helios there is no front mounted headphone socket, so the Chiron adapter cable is needed, and sounds superb to my ears. I imagine others might use the XLRs instead if it suited their setup and worked better with their headphones, and there will be a Chiron cable suitable for that. For the Utopias the RCAs were fine ... amazingly good, in fact!
