Benfits of upgraded connectors

You guys must practice this. ;-) I don't disagree that I can not hear any difference between chassis mounted connectors, and no doubt there is a lot of bullshit, over priced accessory items. There is benefit to buying the $5 set, rather than the $3.50 set only in that they grip a little tighter and don't corrode as fast. But on a cable? That, IME, is usually easy to hear because in the least the connector is a resistor in the path.

Try it yourself if you're into diy. You can make an IC from solid strand copper magnet wire, or silver. Also get a pair of copper and silver ends. Swap them around and see what you think.

Or, keep reading what someone else tells you to hear.

Well Schipo, I am speechless! 'cause all of us we have so many vivid memories about testing especially speaker cables.
Maybe what this guy said is true about some McIntosh or perhaps a few more set-ups, or as I'm about to suspect, the whole thing depends of electrical charachteristics between components. But everything has a different idiosyncrasy because of this ! So, we have to explore it's matching abilities, trying to control them & bring some balance.
I really appreciate your thought about "changing the guide" and I'm greatful that you remind me this !
Thank you & I have to say that your post somehow acts as a break to my will to purchase some Oyaide 004 unless I can manage to A/B test them with the stock connectors.

A friend of mine just upgraded. He has $500 spades on his $200 cables and it changed everything. His CD's now sound like vinyl and the sound stage is in the other room out into the garage. BTW, he is also using the cable elevators, so that may play some part in it.

A sonic benefit? Depends on the quality of your System.
The AES (Audio Eng. Society) has made the Standards for the ability of signal transfer
100=copper
90.4= Gold
106=Silver
...and so on, there are also some very low numbers available.
Anyway, no matter what you like or hate, Silver can carry 6% more information than any other material.
When you use gold connectors (pure wire or similar) your loss only based on this will be more than 15%.
When we check the materials in most High End units, in general there is very low number material used (=cheap, like mixtures with brass for example, these will be "improved" with Gold plating). Based on this, it is pretty normal, that most users can't hear any difference when they do a "comparison". the reason is found mainly in these inferior parts which are used. When only AES Standard from 60 is used, what do you expect?
A Signal can't be improved, all you can do is to keep it as good as possible.
Is this the secret to get better sound?
Who knows? I think, Yes, but only when done right.
