Disagree on Harbeth, certainly the "snake oil" part. Shaw is one of the few openly science-based (mostly) spokespersons (see my signature quote from him), and the more recent models are nicely flat on-axis. I agree Harbeth high end dispersion is F'd up, (gap in the presence region and chaotic way up) but solid through the critical midrange and gives a pleasing, clean, enveloping sound. What can I tell you, I own Revel F228Be and Harbeth SHL5+AE and I enjoy them both, with position-specific EQ applied. The Revels are far more flexible in terms of listening position. The Harbeths are a good speaker for my NYC apartment (see my photo avatar with my cat in the listening position), while the Revels fill a large and reflective modern 'great room' in my weekend place.
If you visit the Harbeth forum, you'll see Shaw inveighing about cable nonsense, break-in nonsense, amplifier nonsense, etc. He does engage in some hand-waving about driver materials, and you'll notice directivity is rarely discussed (moderated out). Their view on resonances is debatable, but he debates it on audible thresholds and physical realities, not magical qualities or inaudible quantitities. I'd say he's an objectivist stuck optimizing older technologies, but they've optimized quite well.
