Slightly off topic but still on (keep reading and you'll see what I mean) I purchased the Nano 300 version. Solely for use for ceremonies and background music type applications.

So far very impressed, it's really good so I can only imagine how good the 600 is! The only thing I'm struggling with is a speaker pole. The hole for the pole on the 300 is smaller than the 600 and not threaded. I'm struggling to find something that fits. I know HK do the pukka Nano pole with cables and bag etc but it has some not so great reviews and I don't like the look of it. Any ideas of what will fit? The recess in the 300 is approx 1" wide and 2 and a bit deep. I've scoured the usual suspects but no joy.
