Emotiva Xpa-5 + Rti A9/Csi A6

Hi all. I just received my RTi A9's today, and my Emotiva XPA-5 and CSi A6 center are on the way. I plan to bi-amp the A9's sending them a total of 420 watts each. With the 5th, 210 watt channel I am going to run the A6 center. My question is do you think that will sound good? Do you think the A9's could over power the center? Or vice versa? I am also going to be picking up 2 pairs of the the FXi A6's and I am wondering 2 things about those. First, do they have dual binding posts for bi-amping? And secondly if they do, I plan on sending each speaker 160 watts (bi-amped). Would they sound evenly matched with the rest of the system or not? Based on the specs for the speakers it seems like its going to be an awesome match up, but I just wanted to check and see you guys think.

    How are you sending the signal to each channel of the amp to bi-amp the RTIA9s? If you are using a cable splitter, you are doing yourself a major disservice. A receiver or processor with front and zone outs is the best method.

    I was planning on using a digital coax (RCA) line, and split it for 2 channels. Is this not good to do? If not, why? I am using a Harman Kardon 254 receiver. It has 8 pre outs and 2 zones. How would I wire it to do what you are talking about?

    With the XPA-5 there really is no need to make it so complicated since it has enough power to drive your speakers to their full potential without the extra wiring. I say hook it up the regular way & enjoy.

    I agree that XPA-5 is plenty powerful to run the RTIa9s with only two channels, but then again more power is always fun. Read your manual to learn how to hookup your amps. I'm not familiar with your unit. But, basically you are going to have the receiver send the same signal from the front pre outs and the zone outs.

    Using cables to physically split the signal results in massive reductions in sound quality. This is especially true for the mid and upper ranges.
