Comparing Persperctive2's to Harbeth SHL5's is is probably not a fair fight (like taking a knife to a gun fight).
I'd be interested to hear how the Perspective2 compares to Harbeth 40.2 / 40.3's. Having owned 40.1's for about 8 years and now owning 40.2 Anni's, I can say the 40.2's are better than their predecessors with drums and transparency, but the 40.1's are a touch better with female vocals and are more full bodied and rich sounding.
