I don't want to sound rude but I fail to see how pure cotton and Douglas Fir cardboard will make electric signals transfer better.

I will agree that aesthetics are nice in open systems where everything is seen and that it can be important to make you feel good about your system. Cheap Radioshack red and white RCA cables can look very undesirable and I will pay a bit more to get a better look and physical quality

However that being said, I personally, would not buy from this company as their marketing has gone to great lengths to try and trick me into thinking that their cables sound sooo much better that I will be astounded or 'need a diaper' as they so elegantly mention. My own practicality is offended by such marketing tactics and I do my best to not support such companies.

Just expressing my opinion. In the end, you should do what is in your own means to make you happy, long term, about any decision. My happiness is irrelevant to your system.
