with all due respect, just because I give suggestions to the people here doesn't mean that i have to hear the m5s to get an idea about how it sounds. Sometimes, experience tells how a device might sound. I am telling you this based on my experience with my fiio q5 on pc
I just can't see how your best guess would be any help to anyone as it is just that, a guess....
If you can indeed predict what something sounds by looking at a picture of it I'll stand corrected
And what's 100% of sound lol?
