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)
Hi I've only used 2 with my dCS. Stock and a Audioquest Diamond...the Diamond does improve over stock...I just haven't compared it to others...
any other recommendation from the user of crystal,
siltech cable?
Look for a Revelation fire wire....
