Can anyone tell me if the O2 has noise floor with Shure 535? The 535s are extremely sensitive and every amp I own produces a hiss when nothings playing - even with the sansa clip famous for low-impedance iems
NoldirHey thanks for replying. What do you mean by "full open"? Do you have an IEM with really high sensitivity (e.g. UE), can you try to play some music and then pause and see if there's a zzzzzzz playing
