Closed bassy cans, much different then the 800's. Also the X2 were going to use be used for console gaming but I decided against it so thats why I am returning them. Can only dedicate money to either the amp/dac or the closed bassy cans.
I suppose... Have you considered a discounted Mad Dog for a fraction of the price?
Snagged a pair yesterday as well but for 210 plus tax. So around 230 but they said like new. What was the condition on yours?
Very Good. In my experience, there's not much difference.
