Right now, I'm having more fun listening to music with my IE7 IEMs then the HD-595. Not sure if it's just the difference in using an IEM vs. a full size headphone, but perhaps I need to try something new.
My source is a Claro Halo soundcard that should be able to drive most headphones I think.
Should I stick with the Sennheiser sound or expand my horizons? I guess, I need something more 'fun' sounding, perhaps more bass will help (as long as it doesn't muffle clarity).
My budget is about $500 or less.
