I was quite certain my comments about the 2 Pi's sonics were quite positive. I'm pretty sure after a couple of weeks the highs well round off a little and that would fit my taste well. To reiterate, after having listened for over 10 hours, the 2 Pi sound quite nice. The highs can be a bit shouty at times, but the bass is fantastic IMO. I guess I just haven't gotten used to bookshelves with such bass definitions.
By the way, I've moved the 2PIs of the mini stand and onto the floor with a DH Sound jumbo cones propping up the front. This added a bit more bass and warmth, which tamed the highs a little.
