Audiophiles hifi appreciation thread old and new

Right I've finally decided to invest in some proper speakers. I've done a bit of thinking and believe that ~1k is a decent price point for used/refurbished bookshelf speakers able to fill my office (a 6x5m space with pitched ceiling).

I'm pretty much decided on a second hand pair of KEF's LS50s, having been around the houses on the LSX ii's which I doubt will fill the room. But I wanted to post here for a final sense check. Here are my needs:

• Must be active, and support AirPlay, but expandable into a modular system
  
• power appropriate to a 6x5m room that could also do double duty as monitors for production (I use a set of AiAiAi studio 'phones currently)
  
• Aestetically they need to fit in a minimalist/natural vibe, lots of raw oak, white/black or ink/yellow contrasts.
  
  

Thoughts appreciated, looking to buy this month.

PS my neighbour is a professional musician and has successfully convinced me that paying extortionate amounts for speakers these days isn't worth it, as the loss is so often in the recording (did you let the mic warm up for 24 hours before using it etc etc). I won't hear your calls to spend significantly more because you've sold fewer albums than him.
