Hi!<br />
<br />
I actually have about the same setup, m1 dac, m1 hpa but a hiface evo for usb to xlr.<br />
<br />
Currently I got hd650s but I have been looking at something better.<br />
Question is, can I really benefit from Sennheiser's top of the line with this rather low end setup?<br />
<br />
Regards<br />
Henrik
