Biwiring make any sense?

Bi-amping indeed offers a practical and effective way to optimize the performance of your speakers by dedicating different amplifiers to the high-frequency (HF) and low-frequency (LF) compartments. By using a low-wattage Class A or tube amp for the HF, you can achieve a sweeter, more refined sound in the treble range. On the other hand, a higher-wattage solid-state amp can provide the necessary power and control for the LF, delivering tighter and more impactful bass.

Active crossover systems work on a similar principle by splitting the audio signal into different frequency bands before amplification. This allows each amplifier to handle a specific range, further enhancing the precision and clarity of the sound. Both approaches can significantly improve the overall performance of your audio system, offering more flexibility and control over the sound quality.

If you've already used low-gauge speaker cables, the sonic benefits of bi-wiring are usually limited. With speakers as good as yours, you owe it to yourself to explore bi-amping to maximize their potential. An integrated amp like the one you have isn't going to do them justice.

@phusis ... but ultimately I prefer using similar amps top to bottom actively (class A/B solid state as is), which is to say all the way down into the subs region to aid overall coherency and tonal imprinting.

Tonality is very much founded in conjunction with the lower octaves, the extent of which actually surprised me, and the problem with shifts in tonal balance using different amps is potentially exacerbated with a combination of very different amp topologies/principles...

I completely agree if we are discussing vertical bi-amping, where one amp powers one speaker and the second amp powers the other; in this case, the amps would need to be matched to achieve the best performance.

In my case of horizontal bi-amping, which I believe is the context here, I was fortunate that the low-wattage class A amp I use for the tweeters has good synergy with the speakers. Although the class A amp lacks gain control, both the class A/B and D amps I’ve used for the woofers have gain controls, allowing me to fine-tune the loudness until tonal balance between the high and low ends is achieved. I’m pleased with the sound, though I believe this experience might be dependent on the specific speakers and amplifiers used, making it difficult to generalize.

For those wizards who think they know everything...
