1. Vertical Biamping 

Vertical biamplification requires the dedication of a single stereo amplifier 
for the left speaker, and another stereo amplifier for the right speaker. This 
configuration improves channel separation and can improve imaging 
slightly. If your preamp does not have two sets of left/right outputs, you will 
need a pair of Y-adapters or a signal splitter, such as a dual amp balancer, 
which will also allow adjustment of subwoofer/satellite input levels. 

 

2. Horizontal Biamping 

Any two stereo amplifiers may be utilized in horizontal biamplification. 
Many audiophiles prefer the "sweetness" of tubes on the satellite portion 
of the loudspeaker while favoring the "control and weight" of solid state 
amplifiers on the subwoofer section. The biggest drawback of such a 
marriage of amplification is that the two amplifiers may have different input 
sensitivities or output polarities. Differences in the input sensitivities may 
be overcome by using a dual amp balancer. This unit allows independent 
balancing of the left subwoofer/satellite ratio and right subwoofer/satellite 
ratio. It's also a good idea to check the owner's manuals to establish if the 
amplifiers are inverting or non-inverting. If the two amplifiers are of 
opposite polarity, then you should reverse the polarity at the inputs of
