It seems to be a feature of the amp, skylab in his review could compare it to loads of other amps and noticed the hiss, too.
I don't want to use higher impedance adapters because they would change the sound signature too much.
Maybe I will ask later when the amp becomes more wide-spread here.
Maybe in the DIY forum.
Any hiss from cables? I think cables don't do a lot to the sound.
I'm thinking about modding the amp itself. But well - considering the hiss and sound signature adding a 30 Ohm resistor would probably help with any cans a bit - it could 'wake up' the highs and remove some hiss.
