Ash, If your using the pioneer with SACD/DVD-A it would be a must have. Being able to set individual crossover frequencies for each group of speakers would be the ideal solution given that the pioneer has limited bass management capabilities. I had the pioneer 563 which gave me two settings for bass management. Large which sent a full range signal to all speakers or small with the crossover set to 120hz/200hz for SACD/DVD-A respectfully. I believe the 578 does the same. If I had an icbm at the time I would have crossed over my fronts to 60, and my center at 80 or 100.

You can also find Icbm's on audiogon and ebay as well for around 200. I've seen them go as low as 150 plus shipping.
