OK, I got anxious, and I went ahead and clicked the 'order' button. 340s front, 200s rear, STF-3, HK 635.
I'd been through the system advisor half a dozen times, nearly clicking 'order', before finally going through on impulse. As it was, I had to call up and change the order, once I re-measured my wall and realized that the 170s wouldn't fit where I wanted to put them.
Has anyone posted what they expect from the "special" on the HK 635? You can pick one out at PriceGrabber for 50-60 less (and even save on California state sales tax), but I do like having everything come at once, so I'm not tempted to hook up my new speakers with the old receiver or vice versa.
I even went to bluejeanscable and got a couple of runs of 12-gauge to replace the 18 AWG I've been using for my (now) dinky surrounds.
