We know Jons sounds good http://taperssection.com/index.php?topic=159568.0 , We can assume follows does too
are the differences in cost worth it based on the rest of the design/setup? Thats a personal thing each individual needs to weigh.
This. As I see it these are the questions:
1. Is there a manufacturer-based solution? (For Schoeps, yes, AKG, sort-of (the out-of-production CK1x), Gefell, no)
2. Do you like the price? (and if you have a branded alternative, relative to that alternative?)
3. Do you like the sound?
4. Does the convenience/form factor improve you rig?
5. Does it work with your existing stuff?
To me, the AKG and Gefell solutions are the most exciting because they don't have any existing in-production product they compete with. Not that the Schoeps solution doesn't also have good things to say for it, but it obviously has Schoeps-branded products to compete against.
As to the price of one set vs. the other, well, the prices for both ought to be what the market will bear. Once they've both seen more time in the field I am sure people will have opinions. And what is right for one person may not be for another.
