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 it.
I have to admit that I need to learn the word "sound stage", "airy", "analytical". But here is my short review with my only standard being the original px100 and my local church band which i helped set. Listening on my new equipment tells me about good music and mastering. Bass and drums become more natural and closer to reality than the bass head px100. Sound stage is very small if your ear is not trained to differentiate from the laptop soundcard. But instrument separation, vocal pump is the keyword. A/b ing have revealed it to me. And yes, i must say that all music become more engaging, not to mention those background music on movies too.
i am now following this forum to see which cheap tube i should get. Thanks guys.
Oh i also sandpapered the tube cover so i can unplug them easily.
*** update: the culprit for the underperfomance is the driver. After i installed asio4all and winamp with its plugin, then changing the midi output in the winamp, then turning off the input of aune in the asio properties, the sounds come up much louder. And the correct airiness. This is a lot of improvement for my k240 headphone.

This is probably because of your headphones! 6922EH tube is among with the biggest & airy soundstage tubes I have heard with Aune T1. 6N23P reflektor logo tube - this is very narrow and foward sounding tube for T1. When I first jumped from PC integrated soundcard to Aune T1 I couldn`t belive what my ears had missed. Even totally music-stranger should notice huge difference!
