I'm planning on pairing these with the K7XXs and a speaker set.
1. Would that be a good pair?
2. Where can I find more information about audio products and where I can get more knowledge of them.
3. What are the different modes on this DAC?
Cetea1) yes I have the k7xx and they pair good. More than enough power.
2)everywhere online.
3) modes? Like inputs? It has USB, optical, RCA, you can find all this out by simply looking at pictures of the back of the M6 or reading details and specs. Very easy to use menu it's one little knob/button that does everything.
