Have an older Grado SR325e's that do a decent job w/ bass. Recently replaced ear pads w/ larger/thicker over-the-ear pads. Really enjoy, but just won't fit as nicely as Senn HD650's or my Philips Fidelio X2HR's (still really enjoy these thru my old Benchmark DAC1. IF... I wanted to spend $2k I doubt I''d go with the GS3000x.
