And the SNOW award (Social Negative Of the Week) for the week ending 9/21 goes to Sdrconsultant, for comparing a very fine speaker to a pair of laundry tubs and wooden spoons. Hang out here on AG long enough, and eventually you'll read the equivalent of Fonzie jumping the shark, 4 buses, a 747 and a pair of llamas. That post may have been it.
Fortunately, it was so inane that unless the OP's IQ is lower than the number on Derek Jeter's uniform, his quest won't be derailed by 2nd thoughts about a speaker he's likely ALREADY HEARD or that his brother has likely ALREADY HEARD and likes because, let's face it, this probably isn't a case of the OP waking up one morning with the realization that he needed a gift for this brother's birthday and him thinking..."I could buy him a tie...or a new socket wrench set...I know he'd like a new putter...oh wait, I bet he'd like a pair of B&W 801D speakers!"
To the OP, if it's a birthday gift then you've got a deadline - I'd call every B&W dealer you can looking for them, as well as looking here on AG. I'm guessing that for speakers that size many private sellers may be hesitant to ship, or inexperienced about the process, whereas B&W dealers will be able to move quicker and arrange professional transport more readily. If it were me, and I needed them quickly, I'd do a B&W dealer search from their website and call every dealer in the country, fanning out from the Midwest region. Someone's got to have a trade-in pair. And hope you don't run into too much of the resistance ZD542 mentioned above (and I know what he means). Good luck with your search - that's a heckuva birthday gift, lucky recipient!
