... same goes for the darkvoice 337 with output transformers, the sub bass extension is insane. Deeper than any of my other cans. Surprisingly I have turn the volume down a little when I go from the K701 to the HD650. I always thought the 701 would be easier to drive at 65 ohms... weird.
Floyd DSOTM swirling around in my head as I type this..... Whhhoaaaah!!
I need to give Dark Side of the Moon a go with the HD650.......I have been listening to lots of Bonamassa, as I am putting together his whole library at this time....dude's guitar playing is just flat out mesmerizing to me.
