Stumbling on the Bi-wire technicalities
I outmost admire scientific approaches, in favour of subjective thoughts/evaluations, since the former tends to be black or white/right or wrong (and verifiable to the ambitious people how have the interest, skills and time for this)
A prudently simplified scientific reasoning that makes the results available and understandable to the wide masses, without compromising the scientific validity, is true art to me.
However, I am not following Mr Lesurf approach this time.
1. On the “single cable” arrangement the calculation is made based on a single run of cable. However, on the bi-wired arrangement the calculation is based on double runs of cable. This in itself is causing rudimentary circuit differences due to reduced cable resistance, which has little or nothing to do with the impact of the bi-wire arrangement. A comparison between the bi-wire confirguration and the figure 3. called parallel bi-wire (which is in fact nothing more than double cables in normal configuration) would have been much more scientifically interesting and appropriate.
2. The complete reasoning also neglects the impact of cable inductance. This is likely not a prudent assumption in this situation since inductance is rather dependant on wire gauge. Bi-wiring will double the effective resistance and significantly increase the inductance, as seen by the amplifier, compared to a single wire arrangement using the effective total gauge of the bi-wire cable.
3. Finally I think it is a awfully complex reasoning to prove that reducing the cable resistance by half will have an at least theoretical impact (additionally without knowing it due to the muddled reasoning)
Personally I find this article
Why bi-wiring has no benefits more of an understandable read about the impact of bi-wiring. Although perhaps not the final say on this subject, it gives a good introduction and debunks some of the most notoriously proposed bi-wire benefits.
