I've sold my T1.3 just to finance other headphones and move around this Beyers world (have to keep my money quite realistic in this hobby). I agree there is no other HP that sounds like that. Capability of new 32 ohm driver is really insane. I do believe it is more capable then old 600ohm one. I went for T1.2, DT1990, DT177X, Xelentos after just to have my own experience with them and i have to say, nothing sounds like T1.3, nothing makes me say to myself 'wow, woooow' listening to the same songs over and over again. The problem I had with them was only that they cannot be your only headphones. Sound is coloured, lets be true about that. Because of that part of my collection sounded heavenly and part like total out of place muddy rubbish. I do believe i will return to this someday when i can just put them on stand and don't count every single $. I love that Beyer didn't hold on to Harman curve and brought something different to the market (like we are lacking neutral and harman tuned cans from every single company...). I hope 4th gen will no differ much from this, just a bit of refined tuning with mids which rejects many.
Referring this to other Beyers;
T1.2 brought tuning to much more comfortable place, where most of my music were enjoyable, I love everything they offer as T1s - spaciousness, imaging, detail but after T1.3 i can't get over low end. Extension and punchiness do not exist on this (please Beyer, just make a hybrid of 2 and 3 as 4th gen!).
DT177X i ditched quite quickly - just mud and muddiness, i don't like them at all and i don't know why there is so much love about them around the internet.
Finally DT1990 - they easily become my daily. They are obviously mostly balanced and neutral sounding and they still sounds like Beyer. They extends very well. Everything sounds right with them. Of course they are not at level of T1s, by any means not even close in their capability but they are much greater all around. I do believe they will be my keeper when i will be switching other sets (As fun fact i use them with new T1.2 pads, they sounds more 'fun', a little tribute to T1's).
Hopefully they will hang next to T1.3 or. 4 someday and I will have 3rd pair to play around
