Sometimes, the pseudo-science on these forums is astounding ...
"It had a wider frequency range..." Really? What exactly do you mean by this? Did you measure it using appropriate technology? Is a wider(r) frequency range actually a good thing?
I wouldn’t jump to that conclusion just yet. Find below a quote from a comment made here by Bob Smith...

And the most relevant part is below ( though reading the whole comment would help give you a better idea about the Schroeder Method, a exciting new idea in cable configurations that has many extremely happy users here on Audiogon....see that below....

Noteworthy in the above is the fact that the Capacitance doubles and the upper Cutoff Frequency (where above which the signal begins to be attenuated) almost doubles. So in the event that we “double-up” our audio cables, we actually extend their bandwidth – albeit we are talking in the region of radio frequencies so there is no real benefit there with respect to extending the fundamental audio bandwidth.
What IS significant though is the fact that all of the above leads to a potential reduction in reflected energy and/or standing waves within the cable, and that is because of two primary factors. By lowering the Character Impedance and consequently, raising the Cutoff Frequency, we “push” or force any potential reflections up to twice the frequency at which they would otherwise occur. That then leads to two other outcomes. First, higher frequencies find it more difficult to propagate down the length of any conductor due to the “skin effect,” and are therefore usually attenuated more with respect to those that occur at lower frequencies. As a result, lower magnitude levels of reflected energy translates into less interaction with the Source and Load circuits. That means less potential for the formation of any associated Phase Distortion artifacts as outlined above.
What is being talked about is the cable generated and cable specific noise that occurs in cables, and which can be reduced by simply expanding the bandwidth of the cable. And please note that it was this particular issue that pushed tele-communication companies to adopt fibre-optic networks ( the old wire networks were producing so much cable generated reflection that it was obscuring signal when under heavy load).
And btw it is this extended band-width that seems to the basis of the success of the Shroeder Method style cable ( and shameless plug...our own cables which have a very unusually broad bandwidth )
Hope I expressed that correctly/clearly.
