Hi, i am a new comer in head fi, i am studying in beijing, and thanks to headfi, i bought aune t1. Yes they have none of the 6n11 tube anymore, mine come with eh 6922, which actually sells for usd 12 in China. (Of course i get better warranty :) ). I have used senn px 100 for 4 years and just decided to enjoy more music by getting the akg k240 mk2. Only to find out that other guys "cried" for having a usb dac and amp to power them. So i buy this aune t1, it hurts me a lot that quality is expensive. But yes i also cried the first time i listened to...
