edgewear,
You are making a claim that others have made here: that it takes a really high resolution system for cable differences to become apparent.
1. But as I keep pointing out: People with "lower res" systems have been talking about and reporting differences between cables for ages. You can go to Amazon and find hundreds and hundreds of customer comments on speaker cables and interconnects there, many of these people clearly are not using super high end gear. In fact you can look up cables on amazon costing a mere 14 bucks, and find a hundred people commenting, many on how they clearly made a sonic difference in their system.
Now, if you really need a high resolution system and/or high end cables for the differences to really show, then that implies all these "bottom feeding" folks are imagining things. And if all those people can imagine they are hearing differences every time they buy new cables on their lower end systems, then it just implies the role of imagination in hearing cable differences, which is a problem for anyone, high res system or not.
But IF these people....and the great many over the years with modest systems...are really hearing sonic differences, then it puts the lie to the idea that you need a super high res system to hear them. (And that’s usually the first thing some audiophiles claim to cable skeptics - "you must not have a high resolution enough system!")
2. The scale, and character of audible differences audiophiles often attribute to changing cables are not "subtle" but are often declared as "so obvious, you’d have to be deaf not to hear it." With changes in all manner of sonic attributes. There is no reason to think such obvious differences require some Super Special system. Even a modestly priced, well designed speaker for instance can easily show you very subtle sonic differences (for instance, between one album master and another, even subtle remastering, etc).
