Hi Tony

If I may make so bold....

Is the 5k centre in there as a stop-gap until you upgrade it? If not, can I suggest that you get shot of it with all due haste! It's a good speaker, but it's performance is so dramatically below that of the 8ks that it makes no sense to drag down the performance of an otherwise world class system with a unit which simply can't keep up. I had a 5kc with 6000 L/R and it was outclassed to the point that I decided to run without it as the centre as it just sounded better.

If space is the constraint, the 5200C would be better, but a 5500hc or 7000C (if you can accomodate a vertical centre) would give a real performance boost.

Cheers

George
