Currently I am using an Aragon 4004 mkII(200wpc) on my 2.3tl's, with the jumpers on the Polks. I am looking at a GAS Son of Ampzilla(80wpc). I wondered how it might sound if I used the GAS for the uppers and the Aragon for the mid woofers? I do have the A1 cable and my preamp has 2 main outs. Any Polkies have good results biamping these?
