I just spoke to Kimber about this very subject. I was told unless a person has speakers with large woofers which need the control that heavy gauge speaker cable brings to bass frequencies, the two will sound the same.
Kimber Kable 8tc V.S. 12tc
I have read all the great reviews in TAS and stereophile about the 8tc speaker cables. They are always a recommended product.I can get the 12tc for $60 more.Is it worth it ? I will be buying these without demoing .And they are not listed in the mags . Anyone heard both ?
