BIAMPING makes sense, BIWIRING is in my opinion a waste of time, it is just making the jumpers longer, period....

From the ten lies in audio article:

"...Even fairly sophisticated audiophiles fall for this hocus-pocus. What’s more,loudspeaker manufacturers participate in the sham when they tell you that those two pairs of terminals on the back of the speaker are for biwiring as well as biamping. Some of the most highly respected names in loudspeakers are guilty of this hypocritical genuflection to the tweako sacraments—they are in effect surrendering to the “realities” of the market.
The truth is that biamping makes sense in certain cases, even with a passive crossover, but biwiring is pure voodoo.
If you move one pair of speaker wires to the same terminals where the other pair is connected, absolutely nothing changes electrically. The law of physics that says so is called the superposition principle.
In terms of electronics, the superposition theorem states that any number of voltages applied simultaneously to a linear network will result in a current which is the exact sum of the currents that would result if the voltages were applied individually.
The audio salesman or ’phile who can prove the contrary will be an instant candidate for some truly major scientific prizes and academic honors. At the same time it is only fair to point out that biwiring does no harm. It just doesn’t do anything. Like magnets in your shoes..."

No doubt that getting older is madatory, but to mature still remains optional...Join the M80's team!
