Hi Crion,
It appears you have a lot of knowledge.
One of the posters earlier in the post, I believe it was Fiddler, inferred that the 6000C is different than the 6000 L and R? I have on order two centers, with sequential serial numbers that are apparently the same on the inside as the standard R and L 6000's. I have researched this everywhere on this site and most people concur that the difference is purely visual. Additionally, I have purchased them from a very forthright and experienced Meridian guy who I trust.
Is Fiddler talking about something different? I like the look of the center channels for L and R speakers more. I don't like the gold line and like Plato I like symmetry.
One other question is for a pair of 6000's for HT, is a 5200HC worth the extra money over a 5500HC? I have a pair of 5000HC's in the rear mounted on the ceiling. I don't have the space for a vertical center nor a place to stand the 5000's in the rear.
Thank you very much!
