Quite sure.
The transmission of audio signals is a pretty trivial matter without needs for 'laboratory made' anything.
Very thin cable, single stand or multicore will compromise damping factor once you exceeded a few meters and also subtly alter frequency response due to non-linear power transmission into the 'speaker load (unless the 'speaker has a flatline impedance which is very rare). In effect, expensive, imprecise tone controls at best.
Goes nicely under carpets.
+1 for the suggestion from @Sue Pertwee-Tyr
A few years ago I had DNM connected to a PrimaLuna valve amp. Replaced with NVA LS5, which resulted in a richer, full-bodied sound but still preserved the clarity and timing associated with DNM.
On reflection, DNM can sound a bit anaemic - fast and clear as a bell to be sure, but not the last word in texture and tone.
I'm using DNM cable for years and always liked the "sound" of it more then all other speaker cables I have tried in that time, no matter what speaker or amplifier I have used.
Sometimes it’s best to just walk away Jez!/\ Spot on. An ex mate got some years ago and it certainly made things sound different... I measured the loop resistance of the cable and it was about 1.5 Ohms!! instant damping factor of 5.3 and 16% of the power being wasted in heating the cable!
To point out the obvious for only the 867th time there is nothing special about "speaker cable"... it's just wire and all that is required is that it is thick and that the minimum length is used, both factors to reduce resistance. Beyond that it could be thick twin and earth, wire for car electrics etc etc. It makes no difference that it says "speaker cable" on the packaging. You could even use nice thick cable intended for low voltage lighting uses

Everything said in this thread other than by Robert and myself is bacofoil millinery at its finest
Hello @Cícero Shmidt : The bass is tighter, the midrange and HF are cleaner but not harsh or dry to my ears. Other cables seem to be warmer but to warm/mudding everything and I'm not a guy who likes steril speakers and components, quite the opposite.
I used DNM cable, then musical fidelity lifeline for years, then several others. I now have Van den hul Clearwater speaker cable as part of an all van den hul wiring loom. Its flat-ish and sounds very neutral but dynamic to me. It made a small but positive difference to my system. Worth a try.
I really like the DNM I/Cs, especially with Eichmann plugs. Been a while since I heard the speaker cable, but also remember being very impressed with it. Certainly an improvement on NACA5...
DNM Reson is one of those cables actually engineered to be "different"
The resistance is significant, but also important is the large spacing, that makes a high inductance that is enough to roll off at 20 kHz noticeably
