I'm confused about the comment regarding KEF Muon being a copy of the Dynaudio C4. I just don't see any sort of resemblance. The Muon, introduced in 2008 is an all-aluminum cabinet shell with activated carbon damping material lining it. The Muon carries 4 front-firing and 2 rear-firing 10" low frequency drivers, 1 low-midrange 10", 5" upper midrange and one 1" aluminum tweeter. And it's a closed-box speaker.
The Dynaudio C4 is a conventional MDF, wood, and metal cabinet, has two 8" woofers, two 6" midrange, and twin 1-1/8" Esostar2 soft dome tweeters. It is a rear ported box. I'm not sure when it came out, but I doubt it was as far back as 2008.
Lastly, the list price on Muon is $220,000US, not $150,000US. These two speakers couldn't be more different in technology, drivers, cabinets, though they could potentially be priced further apart. ;)
