Dan,
The Shure's are electret, are you using the SM81? That is an electret. True, non electret condensors will be from manufacturers like AKG, Sennheiser, and of course the Neuman U67 tube mic. Many of them will be in large cases to hold the electronics needed to convert the condensor output to a useable signal. Many mics are coming out that look like classic mics with big cases and heads that are electrets made to look like a classic. Remember that each mic has it's own distinctive sound and good audio people can tell a mic (model) by listening to it.
