Dan,
I would hardly call Newforms obscure at this point and they are rarely seen for sale in the used market.
And secondly, if you buy locally, you have already paid for shipping, marketing, commissions, sales taxes, the retailers and the manufacturers insurance, retail rent, etc. When you "add it all up", it just doesn't "add up" to ignore buying direct. Like it or not, the web will continue to change the way we do business. I for one like the opportunities it presents.
I personally believe I would have had to pay two or three times as much through the retail system to get these phenomenal speakers.
There is nothing in the price range of the 645's that can touch them. IMHO
(And no, I am not associated with Newform in any way or any other audio tentacle for that matter)
