More high-end version of 6N23-EB? EB is already "high-end" military version. It`s just not so good tube sonically for the genres you listen. Or did you mean 6922EH? You could get gold pin 6922EH but imho it`s pointless. And ditching one tube just because you got broken/bad one is also stupid imo. It is great cheap tube for your genres. You could just as easily get some other more expensive tube that will go bad same way.
Firstly figure out if it`s tube that is causing your Aune T1 problems or not and then start thinking about other more expensive tubes. Lets say you are going to get tube worth around 50$ and when you get it you discover your Aune T1 still having same problems? It isn`t fun, isn`t it?
Dude, start reading this forum. I already gave you recommendations and the are lot of information about tubes in this thread. And sorry for what I`m about to say - stop being p u s s y about tubes breaking and wanting more durable tubes! Like Salvatore already told you, tubes are like light bulbs, they don`t last forever and you never know how good tube you get. If you buy a brand new tube it might sound awful at the beginning. It takes time to burn it in and when it does, it probably has it`s best sounding period between 90% to 60% from the tube lifetime. Under 60% of tube lifetime left, it probably gets worse, maybe increased hiss, hum, distortion, uneven channels etc. Of course these are rough figures I`m giving but just to bring you down on earth. I`m going to repeat my recommendation - for headphones and those genres you mentioned, get cheap NOS Tungsram PCC88 from ebay. And if it calms your mind - PCC88 should last longer due to higher heater voltage specification.
