Hi all, did anyone ever notice trying to use your DAP with and without case?
with blind test, i can hear the difference in between.
Gear : FiiO M11 + K'S Bell Ti

without the case, the sounds are more refined and "shouty".
before, i check that each DAC have a temperature error offset, and off course, using a case will make the hear dissipation worse than no case.
the sillicone will keep the heat inside.
but is it because of this?

and i also notice, some of the aftermarket cases are made with a hole on the back.

anyone can give me an anwer?

thanks and cheers.
