"AT will be coming out with omni heads for the 853's shortly and when they do, they will fit with no adapters"
That's odd, AT already came out with omni's for the 853's and they didn't need adapters. Maybe you're talking about the 933's or the 943's which require an adaptor to use the 853 caps?
This was the answer I recieved when I asked for omni's caps for the CMC-4 (AT853). :-/
This got me thinking....are there adapters for 853's to take 933/43 caps? I'm not sure why one would want to, but just curious. Otherwise, the above doesn't make sense to me.
AT933/943 are the smaller diameter bodies/caps (around 8mm diameter), while AT853 are the bigger size (approx 12mm diameter). I believe 933 are the older version of the small caps, while AT943 are the newer version.
Anyway you can get adapters to fit '853 caps onto 933/943 bodies. But not the other way around.
By the way, I was surprised to learn that 853 caps also fit on AT831 bodies too! The bodies are somewhere in between, maybe 10mm diameter, but the caps have the same thread. It is probably not officially compatable, but it appears to work. So if anyone out there has *any* of the bodies (933/943, 831, or 853), go ahead and try some 853 caps. I guess the newer caps are fair game too, though the prices may be higher. Another thing, it is only subjective, but my impression is that 831 caps are not as good as the 853s. I have not tried the (smaller) 933/943 caps yet, but I'm guessing 853 will sound better.
