Who says cables don't make a difference?

Funny, after all these years, people still say things like "you wasted all that money on cables". 
There are still those who believe cables don't make a difference.
I once did marketing for a cable line I consider to be about the best-Stealth Audio Cables. 
One CES, I walked the rooms with the designer/owner, Serguei Timachev. He carried a pair of his then new Indra interconnects. Going from room to room he asked the room runners to replace their source to preamp IC with the Indra. There was not one that was not completely flabbergasted and said that the Indras blew away what they were using. That was the skyrocketing of Indra and Stealth. The Indra became one of the best reviewed cables ever.
Serguei now makes the Sakra-an IC that blows away the Indra!
I don't understand why some still do not value cables as much as I.
I’m afraid I’m going to have to recuse myself from this thread, as fun as it’s been. I don’t use cables any more, or power cords, they all introduce distortion and noise. Even the best ones, so I hopped off the AC train and went all battery power. If thy eye offend thee cut it out. No more pencils no more books, no more teacher’s dirty looks. 😡
Power Cords too!
Last night I decided to replace a $800 PC connecting my Core Power 1800 PLC to a 20 amp dedicated line with a Wire World Electra 7, a mere $240 MSRP. That one change brought more out of my Emerald Physics KCIIs than I ever could have hoped for
I would say if you are running $800 power cords with $2500 speakers, that may be a bigger issue than quality of the power cord.
I don’t use cables any more
So, the signal from your Walkman to headphones is via Bluetooth?
You’re close. It’s by ESP.
