Just bought a pair of Hifiman HE500s with a Magni/Modi stack. Did a lot of research on different pairs on head-fi and went with the HE500 after trying my friend's HE 400s. Before these I've been using Logitech UE 6000s, which are nice, but these HE500s give way more detail and I'm sure the amp/dac stack will bring out an even better sound.
