I have CA 300/400 and can say without a doubt that the 350's will rock those 802's nicely.More power for sure.I had the 300 on my PMC's(at the time) for a whole month till I got a 400 and WOW on the volume.You have extra headroom for sure.I dont see how 200w/ch will compare to 350w monoblocks.....and I doubt there will be a HUGE difference in sound.Buy the newer 350's(they have WBT speaker posts)...unless you can get a good deal on the older style.
good luck
