Time alignment on the 880 is also fully adjustable. You can also pick specific frequencies for the tweets on an 880prs when in network mode. The 880 has a 16band independent L/R EQ and the Eclipse does not and i will still take a graphic over a parametric just about any day. All of the slope modes you mention on the Eclipse can also be reached with an 880 when used in conjunction with just about any amp. And then the 880 still looks nicer and costs almost half the price. Ill state my point again. Get an 880 and your sound will be on par with a Cd7100. Then you'll have a nice $350 to put towards your install, your speakers, sub stage or anything you want. The end result will be a nicer sounding system. If money isnt a problem to you, forget about both head units and get the H701 combo.
