Advantages of bi-wire?

Hi Lynne,

Besides the possibility that biwiring will not be helpful in many cases, some prior threads make clear that it can sometimes result in significant degradation of the sound.

If your search of the archives did not turn up the following threads, I think you'll find them to be of interest. Three different people reported that in their systems biwiring resulted in significant bass loss, which was even measurable in one case. Near the end of the threads, I offered a possible explanation:

Also, the following papers by Steve Nugent of Empirical Audio, who participates here as Audioengr, explain some speaker cable effects that might occur at ultrasonic and rf frequencies, that would be affected by biwiring. Which in some cases could conceivably have audible consequences via their effects on the amplifier.

Although one could debate the likelihood that a lot of what Steve describes would be audibly significant, I think his papers get across the idea that biwiring can call into play some subtle technical effects that are essentially unpredictable.

Douglas_schroeder echos my experience when determining whether or not I was going to bi-wire.

With my ProAc D2's the results are convincingly positive. A single run is a downgrade.

I went from using single-wire Analysis Plus Oval 9 with gold plated jumpers on my Unity Audio Signature 1's to shotgun biwire Acoustic Zen Sartori. Huge difference for the better-improved bass extension and slam, better separation of instruments and voices, improved clarity and detail. Now how much of the improvement was due to the biwiring or simnply ugrading to a better cable is the question.--Mrmitch
