If bi-amping is so great, why do some high end speakers not support it?


I’m sure a number of you have much more technical knowledge than I. so I’m wondering: a lot of people stress the value of bi-amping. My speakers (B&W CM9, and Monitor Audio PL100II) both offer the option. I use it on the Monitors, and I think it helps.

But I’ve noticed many speakers upward of $5k, and some more than $50k (e.g., some of Magico) aren’t set up for it.

Am I missing something? Or is this just one of the issues on which there are very different opinions with no way to settle the disagreement?

Thanks folks…

I tied vertical biamping my ML Aerius i speakers using two different amps - one with volume control, and could not get them to sound good/better even when the volumes were carefully matched. I think a monoblock set up using identical amps yields better results.
Wow i must think about that it depends on the design.Some companies such as Magico think single wiring makes for a more coherent sound.
Because of the expense of more power amps, and external crossover difficulties, very few audiophiles bi-amp.

I agree with the above comments. Vandersteen is the exception in that they are designed to be biwired.
