i think rock just means the gold, which is possible. i'll see what savings it offers.
Sorry for the delays, guys. I've got a bunch of procedural stuff just kind of...falling apart on my end. I was delaying the K87 shipping by a few days originally to see if I could get the screws in just for my peace of mind, but I ended up anaphylactically allergic to the insulation I ordered and had to deal with that. Now my packaging foam contractor is a few weeks late... I have capsules just sitting here, waiting to be shipped.
We're getting double the amount of flat k47s done this time, so I shouldn't run out of stock again. This next batch will also be glued diaphragms + different colors for the front and rear wires, since a few people (5/300, but it's weird that it even happened) were running into slipping issues.
