Unless you are sure that the wattage, impedence, etc. is identical between the two, I'd suggest bi-amping (assuming your 602's are biwirable). Even if their spec's do match, I'd still be hesitant to bride them and run them as monoblocks. I'm guessing that the bridged integrated would not exhibit the same tonal qualities as the bridged solo amp. Just a guess though. A little experimenting would answer your question best. Happy listening.
