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?

Replacing the caps do wonders and a relatively cheap fix. Bypassing the APOC in the tweeter is another option. Series 3 did away with that. Are they on stands? The soundanchor dedicated stands really open up and cleanup the sound and bass. Also using good bi wire improves things. These are a few options. My Matrix 802 series 3 are amazing. The caps used are sonicaps for the mid/treble drivers and Dayton caps for the bass. They replaced .89 cent bennic caps that were there. Hope this info works for you.
Can anybody advise how to remove casters on 801 series 2. They don't want to just pull out. They were repaired some time ago under warranty and I was given the choice of series 3 tweeters for the cost of one tweeter. How can I check if the APOC has been bypassed? Does anyone know what the part #'s are for upgraded caps and can a rookie make the change?
Thanks. Can't give them up.
Vivant - I have S3's - the orignal castors have threads so need to be unscrewed.

Cheers
