Blah blah blah....so many people with so much advice and self assuredness. Most have not laid down tons of cash over the years exploring all the different cable designs with various systems and environments. Most of the advice is from a limited perspective or biased mindset. On a well mated system, in a relatively decent environment, recent MIT cables and power cords allow the music to flow unimpeded...no roll offs or compression or lack of detail
That's weird, because when I tested / tried MIT cables they were one of the few that actually rolled off the high end. No need to try all kinds of cable designs when you understand how cables work. I don't need to try a 4000lb car with a 60hp engine to know I am not going to get a 5 second 0-60 time.
b4icu,
You seem to be ignoring L and C because I would say there is a good chance you don't understand how they behave in a system. Take the biggest wires you can find, I don't care, make them 000. If you don't design at the same time for low L, those giant cables can cause audible roll-off at high frequencies. Not subtle, but audible.
Not even talking about the resistance in the voice coil and cross-overs yet which will make that giant cable of little value.
There is a popular cartoon which shows two paths, "Simple but Wrong", and "Complex but right". It is often appropriate.
