Packing:
Personally, I have too much. Elaborate and visually striking packaging. Whether necessarily protective caps must be on the connectors and if you absolutely must take costly cable ties instead of the usual Tüddelbänder, well. Drives the price up and ends up eventually but in the trash. I would have served a simple cardboard packaging. Finally, it depends on the content. And that's okay.
Applying the cable:
Solid plug, reasonable cable cross-section, sufficiently flexible and visually appealing. Only point of criticism: No markings or color distinctions on the plugs. Only on an imprint of the product name on the cable can distinguish the channel position. In case of concealed installation or replacement of components a bit inconvenient. Who knows after many years, where it has now been assigned to the left or right?
Sound:
Well, I do not think much of cable Voodoo, monocrystalline Kupfergedöhns, left or right-handed shields and other Tam Tam around audio cables. ;-)
Reasonable cross-section must be, good shielding and good connectors are required. And that meets the cable. Beauty is in the eye of the beholder, the sound is similar. What for a good sound, may be cruel to others. And a before / after comparison is not very meaningful without level adjustment and direct comparison. So, the cables have brought what?
For me, yes. However, here also a zoo has been replaced different cable partly questionable quality levels. Disorders have disappeared. The playback has become airier, depths something punchier.
Whether it must be cable to the value of a good used car, everyone likes to decide for yourself. In my opinion, these cables are perfectly adequate.
