I need advice on bi amping

Bi-Amp DOES NOT require an external crossover. There is already a cross-over in your speakers, making it impossible for the amplifier to supply power at any frequencies other than what the speaker can take them at.

In almost all woofer crossover circuits (there are always exceptions but rare), there is a series inductor. Effectively what that does is increase in resistance as the frequency goes up. In series with the tweeter is a capacitor that increases in resistance with a decrease in frequency. Yes there is more complexity to it than that, but that is the basics.  What that means is when you bi-amp, the amplifier connected to the woofer, only CAN transmit power and low frequencies. It means the amplifier connected to the tweeter (or tweeter and mid) and only transmit power associated with those frequencies.

In regards to Miller's comment w.r.t. why don't most audiophile bi-amp? For one, most good quality amplifiers have enough capacitance and enough feedback that perturbations in the power supply caused by the bass do not create noticeable pertubations in the the upper frequencies (IM Distortion technically). Many audiophiles like some amps, and don't like others and have no clue what is going on in the circuitry that makes that the case. Most audiophiles I have talked to have never actually even tried to bi-amp.

Me and Miller are in agreement in bass arrays, but I caution against using the term DBA as there are Double Bass Arrays, and what some call Dynamic Bass Arrays (but should just call bass array), and they should not be confused with each other.

Clearthink,

You should probably spend less time on feeble attempts to discredit other posters here, while not offering up any evidence or knowledge to forward an attempt at discrediting, and spend less time on insulting other people here, and spend more time on building your own personal credibility which does not benefit from such personal attacks lacking in substance.

At a minimum, I am sure you are aware that visitors can read both our posts. Where yours is nothing but a personal attack lacking substance, my posts are topically relevant and show a substantial understanding of the underlying technology. While other's may disagree with my conclusions, they will at least acknowledge I do understand the topic being discussed on more than a cursory level.

What conclusion do you think readers will reach with your posts?

Good day.

Those who lack knowledge, understanding, and plain logic often result to personal attack, insult , and derision in an effort to appear thoughtful, authoritative, and expert so from those type of people I actually accept the "insult" as an actual compliment or praise. Thank you heaudio and best of luck to you in you’re journey towards truth!

Are you two done now or do I have to send you to your rooms? ; )
All insight- even though contradictory at times- is an opportunity to learn, so I thank you all. 

I bought the additional amp and will try things out. My thinking is I bi wire each side with a horizontal configuration as the amps are not actually going to be exactly the same even though they are the same model. And here I go into the vortex.

A challenge I see is that the old Citation is set up for two "system" outputs, so one to each amp, but I also need my subs connected. One is a Phase Tech 10, the other an Infinity, both powered. 

With amps that old, careful about channel to channel and amp to amp matching.  If you have an AC volt-meter and a test CD, you can measure it fairly accurately, just keep the frequency at 400Hz and lower on your test signal.  Run the test CD, and measure the output voltage at the amplifier on all channels. Even with speakers connected, at the amp, the voltage should be really close on all channels. A 12% voltage difference is a 1db volume difference if my math skills have not failed me today.

So I received my 2nd Quatre DLH 100 and wired it into the system to run the high pass with my other one run out to a subwoofer and then back to the low pass on my Veritas 2.4s. Everything is sounding great and looks good, too.
