I have brought my T1 to try different headamp with DSP feature including SPL Phonitor's 喇叭模擬功能, although the sound stage can be simulated to 2 ch speaker roughly, the overall sound quality, dynamic and frequency balance lost a lot. Such trade off can not be accepted for getting better sound stage.
By the way, try Beyerdynamic T1, although the sound stage is different to common 2CH speaker system, it is already quite good for enjoying large scale orchestra music.
