Howdy, recent conversation i had with a friend triggered some itching regarding cabling and lack of any evidence/testing that would prove him wrong or right. Im 35 years old with some experience in "listening" devices tho these days im focused more on listening music, still since i had the opportunity to listen different setups and ABX cable switching (VDH revolution, goertz, mogami, diy stuff) i can confirm that there are sonic differences between them. The part that triggered me the most in the conversation with my friend (oracle employee with substantial background in audio) was the following (ill translate / quote him).
"There is no reason to make cable braids, its not a differential signal, it creates a load on transistors and slows down the signal"
"Additives in copper only create more resistance"
"There is no directional cable"
"Isolation is irrelevant since you are pushing 20khz through the cable with several volts"
"Both LAN and Coax cables create higher load/strain on the amplifier without benefits and slow down the transition"
"HS cables are bad for LS"
"Use electrician cable for speakers 4mm non solid core its the best cable for the job"
Since he is more of a tech person (sits in a data lab with instruments and tests chips everyday) im inclined to give weight to his opinion, i did hear the difference in sound with cable changes but what are those changes and is it shifting the sound from "no influence from source to destination" or is it acting as a EQ of a sort, what part of it makes the change we perceive.
TLDR: Can we test cables, are there any measurements that would provide data on how well a cable does its job.
