No one actually knows how to lculate what speaker cable they need

Could you use one at work, at the library, at a friend...

b4icu, maybe there’s a language or communication problem but I already explained it to you - the differences in sound between cables, ANY cables, even between cheap cables and very expensive cables, can be explained SOLELY by directionality. If you wish to be the proverbial ostrich with his head in the sand that’s your prerogative. Besides, I actually do not (rpt not) define the high end strictly by price. It is all about sound, not price. Sometimes price is correlated to sound quality, sometimes it’s not. So I’d appreciate it if you don’t put words in my mouth.

BS flows downhill thus directionality exists.

This thread is still running strong? That is an accomplishment. I thought it trickled down to "0 AWG" a long time ago. Add whatever direction you prefer to avoid another 14 pages of circular discussion and everyone is on her/his merry way.

kalali,

"BS flows downhill thus directionality exists."

I think that plumbers are underappreciated and underpaid. As you pointed out in some way, they know a lot about directionality and narrow points in the flow. Like going from 0 AWG to 8 AWG at the end of the cable. It is still quite a mystery to me why, in this thread, large diameter is a crucial positive influence while narrowing it at the end is negligible.
