I have the same combo but started with the GS1000e! Just picked up the PS500e a day ago - bit of an impulse deal buy, but really enjoying them so far. I figure they're both different enough to warrant keeping them both for the moment as they excel with different songs. It's funny, I used to not be fond of Grado's at all during my earlier years in this hobby, but now they're my go to headphones.
