WOW! I have to say something here.

DPA has to be one of the finest microphone companies in the world. I am so impressed with everything I have from them. Their stuff is pricey but you know what, their workmanship shows why.

I've just purchased a DPA UA0837 stereo boom - the one without the mic clips. Now, I didn't know this beforehand, but the sliders on the boom are designed to hold mic clips with a narrow thread (a la the DPA clips)... . The problem is that the sliders have a kind of groove that ensures that only clips with a very narrow base will fit there.
