I am convinced that having a quality dac is indispensable and necessary when I get to have headphones and a total amp at home, for this reason I use a Merging Nadac with separate power supply, both for the dac part and for the pc part which is preceded by a transformer of isolation.
I also use a dedicated power line exclusively for the hifi system, I remodeled my house 3 years ago and wired all the hifi separately, a Merging recommended Cisco router and exclusive data network.
I also use excellent audio and power cables, and I'm sure that all this has a huge impact on performance, black is much blacker and the dynamic contrasts are perceived even at low volume, only after a certain time your ear gets used to it and would you like even more performance.
