"Vertical" biamping


Some have suggested the use of vertical biamping - two amps of the same model/brand powering all four inputs of my biwireable speakers. I'm curious to hear feedback from those that have attempted it.

It has also been suggested that it might not be worth it if your preamp doesn't support 2 pairs of outputs.

I'm curious to hear from those that have tried vertical biamping in general or possibly even modified their preamp to have multiple outputs in pursuit of this vertical biamping idea.

I'm using a Threshold FET 2 pre amp and a CJ/Sonographe SA250 that I would most likely buy one more of if I pursued this.

Thanks,

Phil

I have been using a vertical bi-amp on my Vandersteen's for about a year. I found it to be one of the most worthwhile improvements that I have EVER made. Vandersteen recommends the vertical biamp over the horizontal. Only one channel of the amp reproduces low frequencies freeing the other channel up for better mids and highs because the power supply of the amp is not bogged down so bad. There is also some benifit to this "unbalancing" of the amps power supply. The only caveat with this is the amps need to be identical with the same input sensitivity(as with any biamp) Vandersteen also recommends NOT using different cables for the upper and lower sections. I can't say if all of this is specific to the Vandersteen speakers. I can say that if anyone feels Vandersteen speakers are layed back and soft sounding(which I hear regularly on this sight), then they haven't heard them set up like this properly. It was amazing what biamping did!
