It would be a tough choice just to choose one. Say you could only pick one. I'd have to think about that one and pairing has a lot to do with that... for my setup with the wa 33 it would be the He1000's if I only had the Dave for headphones it would be the Utopia's. Notice the TC's aren't there not because they aren't excellent headphones but because it takes a a powerful amp to drive them. It is warmer sounding than the lot I have. Ironically the Clear's have a similar signature without the bass slam but are much easier to drive.
