Couldn't afford some measurements to verify claims?

"So, is there any strong objection to my insistence that working with comparison of entire sets of cables is the best method of demonstrating their capacity to change systems?"

What will a set of cables for a receiver consist of?

"The objection that cables are hooked up to components should be seen as a moot point. Try listening without components, just cables."

Did you want to say...

It may simply be my taste, or lack of thereof, but those speakers were not that impressive to me. In fact, I was puzzled by all the praises they got at Capital Audio Fest 2019.

The claim is made that the cable makers are not taking into account the interactions between cables and components. Perhaps for the most obscure makers, but I do not see that contention supported in regard to the larger, more science-driven cable makers.

There are 0 standards in components in audio, therefore no interface standards, therefore a one size fits all is pretty much impossible at least for "perfect" operation. Some general tunings can be done, i.e. like Kimber and others reducing speaker cable inductance, but that also increases capacitance which can have impacts on high bandwidth amplifiers, so, one size fits all, does not work, and bringing up L, C, and R does not matter unless you understand what they do and how they interact with other components.

“...a seemingly poorly designed room CAN sound amazing.”
Maybe to your ears, but the sound by objective measures is not amazing. Distortion can sound subjectively good, but its not correct and is something to be avoided.

A room with one side wall absent cannot by definition sound amazing.  Using conventional two-channel dynamic drivers, imaging will be hopelessly messed up in such a case. Unless one is listening in the extreme near-field, which defeats the purpose of setting up a six-figure ‘big’ system in a large room.

I’m guessing at least half of the posters here would go ballistic at the sight of the word ‘correct’.  But there are correct and incorrect ways to set up a room; there’s no getting around the laws of physics.  

“Some of the supposedly best designed rooms are often horrible sounding.”
No. A correctly constructed and outfitted room will sound right, by definition.

To focus on something relatively minor like cables, while ignoring the laws of acoustics, is something else to be avoided.
