Hi, I am looking to choose between these, or maybe 2803. The 7400 will only be available in January in South Africa, and can't wait to compare them. I already bought my speakers and cables. B&W 603 for front, LCR600 center, 601 x 4 for surrounds. Sub=? What are the crossover frequencies? (80 the lowest?) Can you select different cross freq for different channel, like HK? Anyone with a review of the SR7400?
