Bi Amping... worth it?

Yes, it would be worth it (in my not so humble opinion).

If you got an electronic crossover, you would have to alter your speakers. It is expensive to do it right, so I would just start with passive bi-amping. (The improvement if done right is mind-boggling!)

I use active bi-amping which is the use of an electronic crossover BEFORE the amps. The signal is split into highs and lows before the amps. Passive bi-amping does not split the signal and therefore no electronic crossover is needed, nor is any alteration of the speakers needed.

With active bi-amping the speakers crossovers must then be altered. My set up was designed for me by Dan D'Agostino of Krell fame.
In addition to removing the low pass filter from my bass section, he determined that I also needed to change the polarity, as the speaker designer reversed the phase in the bass section with relation to the min/highs for passive use. (this is not an uncommon practice)
Also the mid/high section of the crossover also was altered.

The electronic crossover board was also designed by him.

Because of him, not me, my system was done right.

Good luck,
Richard

The "power" of the amp has nothing to do with the gain.
For instance, ALL Krell amps have virtually the same gain, regardless of the power rating.

I can't imagine wanting a Krell with only 20 watts per channel.
I think the gain of all Krell amps is 26 or 27db, regardless of size.

Call the Cable Company (www.fatwyre.com) and talk or e-mail Bob. He, I am sure, can custom make a Y-connector of the same cable as you now use.
