Thanks, the S/N seems down on the Panasonic caps...but the sensitivity is down on the panasonic too.

The panasonic capsule is a great capsule but if your planning on doing anything but recording birds it must be modified. The primo capsule for "most" recording does not require any modifications what so ever.. But you can do my 4.7k mod to this capsule and then it will handle anything. They are both good capsules I notice the primo has less bottom end but in an omni that's not such a bad thing. The top end is very much the same on both capsules except the primo is flatter past 20k.
