B&W 801 crossovers


I am debating buying tube crossovers. I have a pair of B#W 801 speakers and was wondering what type of crossover or just have the speaker crossovers rebuilt. If rebuilt who?

I have B&W 801 series 3 and considered the north creek crossover upgrade. Never got around to it.
I loved the North Creek upgrade until I sold the Matrix series for my current N802's. Highly recommended if you can find them.
Vegas,

Get the NC's. Much more managable now fhat teo bixes are used unstead of four.
