Is there a better quality Firewire cable?


I am putting together a Mac, Amarra, Weiss digital front end and need to connect everything using firewire. Long ago I discovered that digital cables also matter, but I have heard little about whether firewire cables matter.

Gents,

I understand your reluctance to avoid a "bits are bits" discussion. And I appreciate the fact that some of you claim that you can hear a difference between digital cables. I can't. Given a cable that can make a good connection to the FireWire (or Toslink, or coax digital) port there can only be a difference if something is terribly wrong with a given cable, or the cable is affecting the upstream or downstream processing.

One of my old physics professors used to say "If you can't explain it, you don't understand it. And if you don't understand it, you cannot be sure what it is that you are actually observing."

So surely one of you can explain to me or have a theory as to how a digital signal can be subject to subtle and random errors? Yes, I'm a differential digital cable non-believer. But I'm willing to be convinced if someone can make a convincing argument. That's all.
Br3098, I will also quote one of my physics professors, "If you think we fully understand nature, you will not make a good physicist. Always keep your eyes open for anomalies."

Pardon me if I respond no further. Life is too short.
Hi Tbg,

I bought my 8N-6P-6PI cable locally in Australia.

The Cable Company lists them (look under Acrolink).

However, I'm pretty certain that they come only in combinations of 4 and 6 pins.
I do not know if firewire cables make a difference, but for peace of mind, I bought Granite digital firewire (800) cables from MacGurus.com for my computer based setup:

Cheers.
Thanks for this, Bryoncunningham, they look good and not too pricey. Interestingly I did not find them in a Google search.
