OK, this will probably sink like the Titanic, but these are my suggestions
1. Take speakers out of the godforsaken cables thread and create a 'Speaker Rigs' forum
2. Create a 'Pro Audio' sub-forum to discuss pro/studio gear which may be of interest to audiophiles and music lovers
3. Create a 'Vintage Audio' sub-forum to discuss all manner of vintage kit
4. Create sub-forums under headhones, sources and amps called 'Budget Gear' - ideally sub $500, but definitely sub 1k. That might be 'budget' in the wider audio universe, but I get the distinct impression that many on Head-Fi wouldnt see a thousand dollar DAC as budget kit ...
Anyway, something to think about. Enjoy your day.
(yes, I know this is Head-Fi not AudioKarma - just take a breath and think about the most popular threads across the forums - you'll soon realise that I'm not as silly as I look )
