I also have a pair of sr60's which make amazing sound for their price. The open design allows for impressive bass but unfortunately also makes them awkward to use in public. Hurt the ears after long listening sessions as well. Toyed with buying the GS1000's but figured I was content with the RS1's and many reviewers actually didn't like the sound of the GS1000's vs. the RS1's so I never pulled the trigger.

M80's(2), VP150, QS8's(4), EP800
