I know, MC was told that it is ok when device stays hot when it works.
But I must to say I was have some issues after more than two hours work in headphones. Main display was shows message about short circuit so i must to unlpug jack and wait when high temperature goes down.
Is it possible in the next firmwares to make possibility to switch off the part of device (AD, second DAC etc) which are not used in this time? When all of them are active, it makes to overheat of device.
