Even with my "mid-fi" dac/amp setup, the T1 still shines and vastly outperforms any other headphones I've used (ie: HD650, K701, DT990, RS1), I did try HD800 before buying the T1 and greatly preferred the T1 since it strikes a greater balance of analytical sound and musicality, the HD800 steered too much to the bright side and weren't very good for trance/house/DnB type music, while the T1 gladly took on the task, in many ways better than the DT990 did. When I first put them on my head, the soundstage put a big grin on my face along with a big "Why didn't I just buy these in the first place?". I listen to lots of different genres of music, so the T1 that do everything very well with no glaring weakness are the perfect headphone for me. Music with lots of layers really put a smile on my face, like Porcupine Tree.
I haven't felt the need to upgrade anything after this setup, I really don't have any peeves or hear any problems in the representation of anything, it's still a treat everyday to throw on these headphones and the $900 USD I paid for them in the FS forums is probably one of the most rewarding purchases I've made in my life, it seems so paltry to the enjoyment. I did however have to buy one of those Wooaudio headphone stands... a banana holder just doesn't do them justice for how nice looking they are.
