SO far I have tried: most of the Utrasone range, the Grado range, one Focal and various mainstream brands which I would be too embarrassed to mention

. That was headphones.
Amps I have not really tried a lot yet. Though the Lehmann has graced my ears and also the little Arcam unit, oh and the Creek.
So far I have not been blown away by the headphones. Saying that the Ultrasone Signature Pro was ok and the Focal passable. The amps faired better only because I did manage to get some headphones to sound OK through them, but hard to tell.
My standards are high as I am trying to replicate the sitting in front of a decent system sound. So I can be over critical.
