nice, that's exactly what I did
I have noticed two problems. First, quality control isn't all that great on the Stax plugs, from what I can tell. So, just because it fits your SR-007 "perfectly", doesn't mean it will fit everyone's within 0.001". I checked around 10 or so plugs and found a good amount of variance, in fact I was rather surprised. The other problem (which really isn't a problem) are the people using the WPI socket. It's around 5-6% smaller, and over time bends the plug connectors so that they don't fit all that well in a properly sized connector.
