Nice Krell combo there, I used to own the KRC-3, lovely thing, subterranean depth.
I'm going to let you in on something about speaker cable, the objectivists have it mostly right by saying that Inductance (L), Capacitance (C) and Resistance (R) i.e. LCR measurements are critical. It is easy to change the sound of a cable by raising the capacitance, because among other things this will allow amps to 'ring' and could even be taken subjectively as a 'more sparkly top end'.
I notice that the cables you're looking at, the twisting pattern gave it away, have a MASSIVE capacitance of 1,199.0 pF/m. As a note of comparison, Van Damme 'HiFi' cable has a capacitance of <97 pF/m.
Speakers cables, to be transparent and an easy load for amplifiers, should be of LOW capacitance and moderate inductance, you cannot have 'low capacitance and low inductance'. Boutique manufacturers will generally have higher capacitance cables touting 'low inductance' as a requirement, which is bollocks. Amps like to see a bit of inductance of their output, it helps to stabilise them. Some 'hairshirt' amps can blow up if used with excessively high capacitance cables, and most will complain.
However, subjectively, I do think that the metal type and purity can make a slight difference in terms of reducing overall 'grain' in the sound, which the Van Damme speaker cable caters for with a UP-LCOFC copper type. Mark Grant does a nice job of terminating these with z-plugs, my favourite connector.
