This is so high quality and solid cable, when you touch it you can be sure you can rely on its sound quality!
I did not do any A/B tests but I can feel how my analogue synths became to shine in high-mids and how bass low end turned to be tight and punchy. Overall the sound is more open, in your face which makes it easier to take decisions during tracking and overdubbing.
For sure you can publish a record with much cheaper wires, but these will improve the quality of your music by let's say 5% and what is more important will help you hear better the source and will make it easier to take some freq wise decisions on eq, or compression, etc.
I always dream of having all vovox cables in my system, so that I can blame only myself if music sucks :)
