Are there alternative stands for the FS-805 D3 (B&W stands for the 805 D3 speakers)?

Sound Anchors are great stands and can be customized depending on the floor you're going to place them on. Not inexpensive but they
WILL get the optimal performance from your choice of speakers. 
They made me custom platforms to place under SF Guarneri Homage stands- beautiful but needed some adjustments.

Go for Gaia by isoacoustics.

Some outlet offer 30 day's return.

I am happy with it under Lansche 4.1 speakers.

I use these Pangea DS400 stands with my Harbeth P3s.They are outstanding!

Thank you i will look in to this! appreciated 

Do not go cheap on stands for the $6000 speakers.  I just purchased a set of the Prestige Series 805 D3 and bought the stands knowing the speakers would be attached/coupled to the stands and not just sit on top of them.  $700 for dedicated stands in not expensive.

tks , any idea where i can get these stands from 700usd? New as far as i know they are 1000usd + tax.
