Is it best to use a 5-channel amp for biamping??


My next amp will be a sunfire (not the signature series). Please advice if buying the 5-channel cinema grand and use its channels in a bi-amp configuration will give me better results as opposed to just getting the two channel stereo amp?

Thanks in advance

But for hybrids like MLs, which Planckscale has, passive biamping has significant advantages.

Passive biamping an ML hybrid separates the stat from the woofer, thus presenting the amps with a less complex load.

The stat panel presents the amp a high impedance at low frequencies and very low impedance (1 to 2 ohms) at high frequencies. The woofer's impedance curve is relatively more flat. Driving them separately makes the amp's job much easier.

I biamp my Aeons with four of the five channels of my Meridian 5-channel amp. This makes the speakers more dynamic - a frequent complaint about hybrids is that they're not dynamic enough.
I should add that by using your 5-channel amp this way you are, in effect, vertically biamping, which works better for Logans than horizontally biamping. Cheers.
Go the the MartinLogan Owners forum and ask for feedback about Sunfire amps. Some are happy; others have issues.
