Passive biamplification questions


I want to know your opinion about the use of two stereo amplifiers in vertical passive biamplification.
My speakers have biwirable or biamp. connectors and my preamplifier has two main outputs, so I can go to passive biamplification without problem.
The passive biamplification really represent an upgrade ?
If the answer is yes: Why it is too difficult to find system that use it ?
Please let me know your experience and opinions.
Thanks,
Carol

You should contact the manufacturer to see if there are any potential problems with bi-amping. Some amplifiers go into oscillation with some speakers in biamp mode.
