It took awhile, but it took literally 100 hours to break in the fronts. The surrounds and sub are still in the breaking-in stage at about 20 hours.
I went all Jamo Concert Series: C 809, C80 Center, C 80 Surround, C 80 sub. For the 7.1 rears, I went with JM Labs Chorus SR700.
The soundstage of the C 809 fronts are excellent. I have the unit in my library, I believe the musciality of the speakers are near-perfect, but a slight touch warm.
The C 80 sub blends [this is what a sub should do - blend, IMO] and just accents the mains without booming. Very happy with the these. [I want to thank the previous posters for their advice].
The C80 Surrounds - enjoyable, but still not completely broken in. Rears take months because even in movies they are not used all the time. When I am watching a movie, I feel immersed without the speakers being harsh, or overbearing. Really, I am involved and not thinking about their sound. I think that is the ultimate testament to surrounds - being uncolored and in the background, coming to life when they are needed.
The C 80 Center - transitions from main to main without the stop and go, "I am on or off." A speaker that will take months to break-in. A speaker that I am very happy with.
The 7.1 rear JM Labs Chorus SR700 - rarely used in movies and never in music.
Al going through a new Yamaha 1800. Next on my shopping list is an amp for the fronts.
