Hi all. Dan
@mrspeakers made an interesting comment on the Ether thread about break in for the Pulse Infinity...

We exchanged brief words about it at London Canjam so I presume I'm one of the two other owners he's spoken to about it. I definitely experienced the same thing...the Infinity went from sounding really closed in and frankly unpleasant to far more open and generally better all around after some days of 24/7 running in (I don't recall precisely how many - more than a few, less than 10 I think).
Worth bearing in mind for anyone who's not immediately blown away by their Pulse (although obviously I can't say if this same running in period applies to other versions).
