Biamping

Bi-amping offers more advantages than just an additional power supply. Vertical bi-amping can offer the same benefits of monoblocks, plus the benefits of bi-amping. Bi-amping reduces the responsibility of each channel, and can offer a lot of flexibility for using active or passive crossovers. Separate amps on each channel reduces crosstalk.

I’m currently running tube monoblocks on the mids and tweeters, and a solid state amp on the woofers in a horizontal bi-amp configuration. I still use the passive crossovers on the speakers, but have the option of adding an active high pass filter for limiting the bass into the amps that drive the mids and tweeters.

With good equipment and a decent system, you should definitely hear a difference. Bi-amping with something like a modest AV receiver is less likely to offer much improvement.

Years ago Bi-amping was the way to go, heck, I briefly had a Tri-amp setup.  But now I’m running a Hegel integrated. Probably because my ears aren’t as good as they were 40 years ago.🙁

My current setup since 8 years :

Audio Research ref 7 CD player

Audio Research  ref 3 preamp

BAT 2 x VK1000 poweramps

B & W 800N speakers .All bi amp . i think it will not be better

Bi-amping requires 2 amps plus an active crossover adjustable to meet the frequency, level, and slope of the original passive design. The benefits are many, most notably a 6dB increase in dynamic range and better woofers control by eliminating the series LP inductor(s) and it's associated resistance from the equation.  The drawbacks are of course cost and the potential of accidentally bypassing any shaping network elements. To avoid the latter, the biamp insertion point must be prior to the shaping network, or the shaping network simulated by a DSP prior to the associated amp. 

So called 'passive' bi-amping, feeding both LF an HF  full range and still maintaining the stock passive crossovers is simply a waste of money. It maintains all the drawbacks, eg cost and complexity, while providing none of the benefits of actual bi-amping.
