There are many superb dacs out there and your headphones are excellent.
The easiest way to know is to borrow a great dac and then listen to the improvments it makes in your system if you can hear and appreciate the difference wether or not it is a speaker or headphone setup it doesn't make a difference then it is a valid upgrade.
We have heard the Merdian Dac nice piece you can do better for less money.
You may want to consider a Lumin X1 the previous reference the S1 has been considered to be one of the best sounding streamer/dacs out there and the new X1 is reported to blow away the S1, at $13k it isn't cheap but for a world class Dac and streamer the price is reasonable the Lumin products are very musical and extremely well designed.
We are also not huge PS audio fans in terms of power products, in our tests the Passive conditioners were better. Look at the Isotek Sigmas fantastic performace for the money.
We have tested many brands of power conditioners from Audience, Shunyatta, Running Springs, Exact Power, Isotek, Audio Magic, Synergistic and a few others.
Best overall Isotek for the money, best performance Audio Magic.
