I'm still game. We never really did anything with this last time, but I'd definitely still be interested. We could probably buy from Digikey, just pool together to make one order. I'd buy several all by myself. Do you think we should make a post on the Group Build forum and see how many hits we get?
Another one I'd like to do a group buy on is Burr Brown opamps. I need OPA 627 and OPA 404 chips. (See "Active Sub Crossover" thread.) I'll buy dozens of them and that alone should allow a quantity discount. So I probably should make a post in the Group Build forum for that too. We all can take advantage of the quantity to get a price break.

We may be able to take advantage of pooling our purchase, even if there's not many others interested (even if only we two). I am interested in the OPA404, OPA627 and the LM3875 and/or LM3886 chips. I am going to buy at least a dozen of each of the Burr Brown op-amps, so you you want some of those, you can get a quantity discount no matter what. On the others - the LM3875 and 3886 - if we each bought 13, we would qualify for a price break. If others decided to join in before we actually place the order, maybe we could get an even better price. Here are the quantity price break points for those four parts at Digi-Key:
Wayne, I've been thinking about the new LM49810 or 11. Acording the the chip designers it's the best sounding one they make. Of course I was just thinking 1 or 2 to hear.
diy audio site has a few threads about it with some of the National engineers discussing their various merits. I know the famed Bob Pease played a significant role in their development.
