OK, now comes the time to disclose my "sources":
Source #1: Sennheiser KE4-211-2. Omni capsule, 5mm diameter, gold mylar diaphragm. I believe this is similar to the Sennheiser MKE2 lav capsule, but without the "sweat" barrier, and seems smoother too. Hrtf, mounted right above the ears. Some windscreen material in front. Mics have 2.2k mod, directly into Edirol R09 plug in power.
Source #2: RTI/Intricon RT-1200 capsule. This is a rectangular capsule, 6mm x 8mm, 2mm thick, with a 2mm diameter hole in the front face. This *may* be related to the Lectrosonics and/or Tram mics. Manufactured in Singapore. These were glued flat on the front of my hat, a bit more forward than the Senns (hence the different image). Directly into Minidisc plug in power, mic in, low sens, pcm recording.
OK, my take on this is that I still prefer #1. Not quite as open sounding (sounds a bit dark), but seems more clear in the mids. Seems to have more detail, and more smoothness/warmth, hence just more pleasant to listen to. Source #2 sounds more natural right away, but I don't think there is as much detail, and there is a very slight "edgyness" that I don't like. I would liken these differences to Nevaton MKE400 (smooth) vs DPA 406x (edgy) mics, but less extreme.
Note: I'm not selling these mics (yet), but I choose to disclose sources in case anyone wants to purchase them. Sennheiser KE4 (bare capsules) are approx $95 each, from Sennheiser industrial division. The RTI/Intricon mics are available only in large quantities (25 or 50 pieces). At this point I'm still searching for something better sounding than the RTI/Intricon, since I don't consider them an improvement over the Sennheisers.
