Coupling Capacitor upgrade? Which one first?

George actually I tried to change The dac output caps with wire. Not too much change. (just a feeling some thing removed :)
Because of this, I started to think amplifier input cap more important than dac output caps(>>>>).
But you guys more experienced than me probably. Maybe someone has similar experience or explanation..

Shows you the Wima's are pretty transparent, just leave them be.

I ordered New wimas from mouser, I will try them next week.Maybe my amp input wimas are fake ones. Maybe it makes a difference. 
What do you think which one is more important caps, amplifier input or dac output?

Just leave the amp ones in, and leave out the dac ones. But then only use that dac with that amp!

I agree with all of @georgehifi 's comments so won't repeat them. The only thing I can think of that could affect the sound is if the roll off is close to the audio frequencies. Seeing as all the MKS2 caps come with the same pin pitch, you could try the 10µF version (which would move the roll off further away from the audio frequencies) although I still doubt that would make much difference.
