No, but most see the PS1 as the king of the grado's, so I don't feel the need for tracking down a HP1000 anymore at all. Don't get me wrong the PS1 is a fantastic headphone, but I wasn't blown away by it at all, it was more like, ok yeah that sounds nice. When I listen to my RS1 for example, I get blown away a couple of times on my listening session. Each to their own offcourse, but the PS1 is not for me at the current prices.
