Triwiring or passive biamping might bring a benefit if the existing single wire or amp is inadequate for the desired volume level. In either case voltage drop along the speaker wire is reduced. In the latter case, current through each amplifier is reduced- and current is the root of many amplifier evils. Passive triamping would also allow distribution of power into the amps (less voltage drop for each from the wall outlet), and *maybe* less power dissipated in each amp.
I certainly agree that if the existing single wires or amp is reasonable for the desired sound level, multi-wiring or passive multi-amping isn't going to give a noticeable sonic benefit. Barely *measurable*, possibly, but it shouldn't be audible.
My point was that jumping straight into active multi-amping is usually a steep learning curve for most people. You need multiple sets of speaker cables, which are (should be!) relatively cheap, simple, quick, and easy to achieve. You'll need those cables and connections labeled and verified before you can multi-wire or multi-amp, so you might as well get that out of the way first. If that step is insurmountable, then you've saved yourself a lot of time and money.
Same with the next step, passive multi-amping. Figure out the multiple amps (or multi-channel amp), the mounting and interconnect cables. Get that all working before the last step.
All I'm saying is instead of making it an all-or-nothing proposition to purchase a shopping cart full of amps, rack, a loudspeaker management processor, interconnects, and speaker cables, the average person can make that investment gradually. And they can test the setup as it progresses. Even if the real payoff doesn't happen until the end.
Passive triamping can, and does offer potential improvements over the two previous as well as simple passive xovers.
I assume that you meant *active* triamping? Again, I agree.
One thing passive crossovers can do(and therefore multi-wiring and passive multi-amping as well) that active multi-amping can't is offer a degree of inherent driver protection from amplifier faults. That's not much of concern for home audio, of course, unless the speakers are extremely valuable...
You can do far, far more with a DSP than you can in the analog domain, either actively or passively.
I think you could do most things in the analog domain- just not as well, as easily, or as cheaply!
