What kind of bulk cable can I use to make DIY ground cable- it has to be
about 15 ft. long- will run from power amp. to Granite Audio Ground Zero device.
The other short groung cable will need to connect power amp to it's separate chassis Power supply.
Follow Ups:
Since wire is system dependant, including GND wiring, I have had great results with using AudioQuest Type 4 Hyperlitz multi-gauge LGC copper cables doing GND duties in my system(s) utilizing balanced power.
The general concesus is that any old wire will do for a GND wire as long as it is of sufficient gauge for the job but I have found that in a high resolution system, this is not the case.
Only U can decide but one can pick up used sets of the Type 4 cables for damn near nothing.

Thanks,
So, would you say, lower (thicker) gauge is better for GND wire?
"So, would you say, lower (thicker) gauge is better for GND wire?"
Not necessarily, it is the construction of the cable. The AQ Type 4 is a basic cable yet is constructed with solid core wires of different gauges and due to it's construction technique, is more immune to resonances than a plain stranded 18 gauge wire sheathed in PVC.
It also depends on the application. I found very little difference when grounding the bottom steel plate on my VPI Scout TT with an 18 gauge stranded PVC sheathed wire from RS vs. a 20 gauge solid core wire. I did however hear quite a difference between the AQ Type 4 and the 18 gauge RS wire when grounding my component rack's steel frame.

Depends wether it is a signal ground or chassis (safety) ground.
You want only one path to a common point (star ground) for audio.
Other grounds that cannot be lifted for safety reasons should be
choked (few turns on a toroid) to keep them from becoming part
of a ground loop that can pick up hum.
If you are going to choke a wire, it harldy matters what type.
Long as it can pass the required number of turns thru the donut.
And its big enough to short out your whole system to ground if
something seriously unsafe (to you the operator) happens. The
choke too can be unsafe if wound too much. It has to pass 60Hz,
or it isn't saving you from anything... Its hard to fix as an
afterthought, grounds are better engineered from the beginning.
If its for a signal ground, then a fancy wire might be in order.
It can't hurt. But I also can't think of any signal ground that
extends out the chassis. You probably looking at safety ground.
And even there, it does no good to be better than your 200ft or
so of solid 16ga copper you got strung through the wall/attic.
Its funny that you would use a Litz wire for ground. But not
consider it for the audio path inside the chassis (see thread
about gold plated silver wire.) You klowns kill me.
Howdy
No need for remarks like "You klowns kill me."
