I bought some cheap and cheerful Richer Sounds branded 4mm shotgun copper cable about 10 years ago and have never considered upgrading... Until now.

Thing is, I am not looking to spend a great deal and so am wondering if there is any point. As I understand it, all copper is pretty much equal?

How rubbish is RS speaker cable? Would something like Van Damme blue offer any noticeable sonic improvement? Or is it just different branding on an essentially identical product?

Unless anyone has a strong view that modest investment will yield results, I'll probably keep as is.

Cheers!
