Recommendation for firewire cable for Weiss DAC20

I am now using Oyaide NeoD firewire cable for my Weiss DAC202 and would like to upgrade the firewire cable.
Any recommendation besides the very expensive crystal cable and siltech firewire? Are they really worth their price?
I prefer the sound signature of the stereovox but it has
no firewire cable (only the Black Cat USB cable)
