Sorry to hear you took a lightning hit - I'm in Brisbane, Australia. We not only get a lot of electrical storms but the power is a tad unreliable compared to the UK. I'd highly recommend one of
these as its kept my kit (and my nerves) solid for a couple of years now (I have one for my hifi gear and two more on our computers etc) and they guarantee kit connected to it up to quite a high value too which shows confidence in the product IMO.
I don't know how the 731s compare to the BR2's though I'm sure Andrew will be along to tell you shortly. I'm been a long term 'Mission' fan and recently bought the MA RS6's and if, like me, you liked Mission, I'm pretty sure you'll like Monitor Audio too - maybe have a listen to the RS1's if your budget allows.
Good Luck either way.
