Spikes or platforms

I own the B&W matrix 803s. I want to know what would offer me the best sound upgrade, getting better spikes, getting a platform rig maybe also with spikes (like the Maple Shade platforms) or the Sound Anchor stands? I think the SOund Anchor are over priced for the 80s stand but then agin, I do not own them.

Also with your suggestions, please let me know if you know a place where I can get the info and product.

Thanks and Happy Listening.
