I'm really quite happy with my K701s. I actually wish they had _less_ bass, but I can live with the level they have. They don't seem to be getting more bass as I use them more, but I know people insist that they get more as burn-in continues *shrug*.
I agree with people who say they're good all-rounder, but I disagree that they don't excel in any way. Between the SA5000, CD3000, K501, and K701 on episiarch's home rig, I thought the 701 excelled in terms of instrument separation while maintaining an involving sound to it with good response across the spectrum. That's really what it's excellence, I've found, is. It combines multiple pleasing qualities into one thing *shrug*. It could stand to excel more in certain areas, but I don't think that means it isn't excelling in other ways. The CD3000 definitely reminded me of my experience with the R10, where I felt like some of my music was getting so 'busy' that I almost felt like I wasn't listening to music and was just lost in some sort of cacaphony. That happened _BIG TIME_ on Pink Floyd's 'The Wall' for me, and I was using the MFSL version which IMHO works *against* this sort of feeling, versus the original.
I've also found my PINT drives it really well, for whatever reason.
