Sain line system cables a hidden giant killer.

I come from an practical engineering background, transmission line theory has been understood for a long time now, all the various materials used in numerable configurations amount to comb filtering at a bespoke cost.

Some of the audio media have done an amazing hatchet job on the audiophile psychology, you can't read a review without an expensive cable being a part of or even making or breaking  reviewed components and of course those with vested financial  interests only too ready to exploit this.

When was the last time you heard of of the specific allowances made for the capacitance and inductance inherent in the speaker cable used by the designer, so you could make an informed decision by numbers in you purchasing.

My comments are not meant as threat, what you spend your money on and the reasoning are subjectively yours.
