I used to have T5s and loved them, especially paired with Corda Stepdance. They were quite bright and bass was weak, but I did not mind that at all as soundstaging and details were excellent. I did not have a proper setup, a full desktop rig, to try them, so it would be hard to say how they perform in an environment like that.
I now have T1s and find them considerably less bright, bass is stronger and very precise. Detail, soundstage - all great. I have paired them with Woo Audio WA2 and believe this to be the ultimate setup. Incredible. The only thing that has recently crossed my mind was to try a Beyerdynamic A1 amplifier that was created with T1s in mind.
