One of my top headphones and I did not change anything on them, no mods. Not as detailed as HD6xx with XLR, but the T-X0 is very enjoyable. It requires a long burn-in because out of the box they were weirdly decent, and sometimes not. I did the burn-in trying to get them ready for modding at modhouse, then I noticed that they sounded much better than out of the box. So I decided to keep them and kept lisenning and comparing them to other headphones. The T-X0 has very nice detail acroos the frequency range and a wide soundstage. Sometimes, and with the right music, it feels like being in a cathedral/chamber listening to perfomers. I will buy the Argons mkIII but I am keeping the T-X0 unmodded to compare it to Argons. Currently running T-X0 on Schiit Magni 3 or Aune X7s with Schiit Moddi 2.
