I want to use 3 of my Harmon/Kardon PA2400 Power Amps to drive my front 3 speakers. Left and Right (Ref 2.2's) are 4 Ohms loads so according to my PowerAmp's manual I can't bridge the amps. This makes the decision easy LeftHi/RightLow in one Stereo Power Amp and RigthHi/LeftLow in another. Both speakers will be Bi-Amped using 2 runs of Silver Anniversary Cable. The Centre channel has more options open to me. My Model 100 is a 6 Ohm load so I could use the power Amp bridged. I only have 1 Silver Anniversary cable running to it, but I have a previously used QED 79 strand still running unused under the floor to the same position. So:- What's the best option for the centre here? 1/ Use 1 Channel of the power amp using 1 run of Silver Anniversary cable, leaving the other available for a passive sub later? 2/ Bridge 2 channels of the power amp together and run through 1 run of Silver Anniversary cable. 3/ Bi-Amp using 79 Strand for Low Freq. and Silver Anniversary for High Freq. I do have another HK PA2400 and a POA-T10 but I want to save them for surround duties once I get a Lex. Thanks, Mark.
