Use of Sterling silver coax for IC & speakers?

I am fabricating speaker cables using OF sterling silver (92.5% silver and 7.5% copper) with silver Bullet Plugs. Does anyone have experience, listening or lab values, with sterling wire sets? I will be running Vandersteen Quatros with a Technics DC class A amp, a Luxman CL34 pre, SME TT and a Benz H2 cartridge.
Thank you for your input!
