Not to pick a fight but this is a perfect example of what I am referring to in a previous post. While I wont argue that certain cables indeed do expand the sound stage and increase the depth of it I also don't believe its safe to say that the same cable offering such "benefits" is doing so because its more accurate to the source then a Mogami or similar studio cable.
I see no technical reason why a Mogami cable is unable to reproduce all the content that is really there to begin with compared to Brand X audiophile cable. Would anyone argue that the ultimate goal of any audio cable is to measure perfect zero's for all LCR values to be considered the "Perfect" transport that changes nothing? I would argue that whichever cable is closest to this ideal is the one you want for something like a long balanced run from PRE to AMP. Length is the enemy in this case.
Obviously the above mentioned perfect cable doesn't exist but there are some that get as close to that ideal as technically possible and I feel Mogami is probably one of them. Any cable measuring well outside of all zero's is simply adding flavor that isn't supposed to be there in the first place.
But with all that said, I wont argue that such truthfulness isn't always the one that sounds better subjectively to some folks, myself included. I've spent a bundle on fancy speaker cables (Kubala Sosna Elation) exactly for this reason. Whatever seasoning they are adding is pleasant to my own ears but I don't fool myself into thinking that its more accurate to the source because of its flavors. If I wanted nothing but truthfulness/accuracy I would use a Mogami for speaker wire instead. My preferred approach these days is to have a cable that adds/subtracts as close to nothing as possible leading all the way up to the Amps and then and only then do I choose to add salt/pepper via speaker wire.
There is plenty of seasoning added by the components themselves along the way as it is. The only way to figure out which cable is most "True" is to measure them and publish the numbers so the buyer can decide for themselves why perhaps the soundstage width and depth maybe so much greater between brands when comparing them.
The expanded soundstage is the result of the reproduction of spatial information, or echos in the recording venue. Or, spatial information may have been added after the music was recorded, so it's artificial. But either way I want to hear it because it is the basis of what forms the illusory experience of being in the recording venue rather than your listening room, or the "you are there" experience. Mogami cable is going to tend towards having a more amporhous soundstage, that is less 3-D and immersive, and sounds more like the performance is in your listening room. The reason this happens is because the copper wire in the Mogami cable, along with it's insulation, overlay a warmth over the sound of your system. This warmth smooths out detail. Besides the soundstage, this is also most apparent in fine details of vocals and string instruments. The additional resolution makes the sonic image seem more realistic, you can hear small details you can't with the Mogami cable. Overall, it's a large step towards higher fidelity and is often what separates a system that is simply good vs one that is excellent and memorable. Just IC cables can make this kind of difference.
On LCR, as I said before, it's not a primary factor in how short cables are going to sound. Metallurgy is by far more important. Publishing specs is mostly going to lead people to form misguided opinions on the cable and how it sounds.
On your KS cables, imo they are "voiced" a certain way. They are warm but maintain as much resolution as possible. Their IC cables tend to be high capacitance designs that sound lush and nice but not exactly super high resolution. They are often a good match with hard-coned speakers with metal, diamond or ribbon tweeters. This means they are not a good contrast with the Mogami cables, if you want to experience the difference I'm talking about you want to demo UPOCC silver cables. I'd be more than happy to send you a pair to try out, no cost, no expectations. I don't even expect you to like them, not everyone wants extremely clear cables, and finding ones without negative side-effects is not easy and the cables won't be cheap. Besides mine, which are actually a silver/gold alloy, other UPOCC silver cables include top end WireWorld and Siltech. Then there is the issue with fakes. If you google "UPOCC silver interconnect cables" the entire top row is counterfeit products. There is at least one company in the list on the 1st page that is not genuine either.
