This item have a very loud humming when it don't play music. You can hear the humming 3 meters far away. But some senior audiophile can accept it becuase the sound is nice when play music. Why so loud humming? because it is AC for filament-type. The DC for filament-type will get less humming, but the sound is not good enough, Factroy don't use DC for this version . Usually, the new tube members are not easy to understand and accept so loud humming. e new tube members are not easy to...
