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

I’ve EQd the room <1000Hz to within +-3db down to about 8Hz. My mic isn’t accurate above that. I’m waiting on my calibrated mic which I’ll get in March.

im using all digital sources ranging from Spotify through flac from HDTracks up to Sacd (Telarc, plus others) and DSD 512. My dac is only good until 24/192, but I have an alternative dac that supports full DSD as well, it’s just not in my main system (it’s only 2 channel). 

So, all things being equal, my system is high-end (RME HDSP, Classé ct-5300, B&W 802N) The cable is high end? The room is ok? The sources are ok? I should hear a difference, right?

" Even with a mid end system, before you lay down your equipment, it needs a proper room and some excellent sources (recordings). Are you sure you have that as a start? "

Ah, are we now back peddling at bit?

Not sure I go along with the presumption that Kimber 12TC are “high end cables.” I guess we need to define what high end cables means.  Kimber does have good name recognition going for him, however. I’ll give him that. By the way sales of fake Kimber 12TC cables appears to be rather brisk on eBay. Maybe I’m missing something.

On another subject I’m not sure why people assume that a given set of components have a certain predictable level of sound quality or that photos of a system reveal anything about how it sounds. There are way too many variables to be able to make such judgements.

Kimber 12TC Electrical Specifications:

(Cp) parallel capacitance: 494 pF / meter - (Ls) series inductance: 0.09 uH / meter - (Rdc) dc loop resistance: 0.005 Ohm / meter.

geoff is correct, here is an ad for fake Kimber 12TC

Neither of those responses really answer my question, other than: we don’t know how it’ll sound.

quite the punt then at $1000 from here: https://www.russandrews.com/kimber-12tc-speaker-cable-biwire-kimber-bananas-31909999101/
