Mistico, don't waste your time. I had the MPS-1,as most know, that kept shutting down at louder levels. Lonnie at Emotiva said to try bi-amping by removing the clip on my speaker terminals and use one amp for the woofers, and the other for the upper drivers.
I told him that others say this is not 'true' bi-amping because of the crossover in the speakers. He said everyone at Axiom telling me that was nuts.
I will say that there was absolutely "no" difference. Any gain, was so minimal a person could not audibly notice.
