Bi-Amping My Mirage 3si's


I would like to change my set-up from Bi-wire to Bi-amp.Is it as easy as running 2 feeds from amp to each speaker (1 to low &1 to hi)and then running y outs on left & right channels on my casablanca and then down to amp?Some questions i have?
1)Will Bi-amping better my set-up
2)Can anyone recommend cables(balanced interconnects& speaker cables)
3)where would i get y outs-i would need balanced type

being your already using a subwoofer I don't think bi amping is going to help any. Are you running the Mirage full range or are they going through the subwoofer crossover first [and then feeding the amplifier]at what frequency is the crossover set if so? or maybe your preamp/processor has subwoofer output connections? what is your configuration it's not very clear to me. bi amping is not as simple as your understanding of it is its more complicated than your description.
Mejames-The Theta Casablanca has a sub out that i do use.It has mnay different crossover points that i use depending on what i'm listening to.Most times i run my M3si's full or cross them at 40hz and let the sub due anything under that.
Can you explain what can make it more complicated?Does it have anything to due with crossovers in my speakers?Let me know.Thanks Kevin
Greetings,

Yes, I did similar to what you're proposing, using four channels of amplification on my two main speakers,only I have Magnepan 1.6QR's. I used Audioquest rca y adapters out of the preamp to split signal to the four amps. I don't know if Audioquest makes a balanced "y" connector/cable or not, but they're as good to try as any company. I understand they make more items than shown on website, so you may have to contact them to ask.

I found bi-amping to be a tremendous benefit. The sense of power and authority was well worth it. I'm using twin subs and still found a great benefit to biamping mains. The sound stage seemed "deeper" with it biamped, like the equipment had a better grip on the signal and reproduced it with more clarity/authority.
