If the DQXS had time alignment it would be perfect. As it is I'll be switching from the PRA-H400 (digital x-over w/ time alignment) that I have now to the PXA-H701 once I get some money. Same EQing and crossover ability as the AudioControl plus ability to accept a digital input and decode 5.1 should I add a DVD head at some point. Same price as the DQXS and if you have an Alpine Ai-Net HU, you can control it from the dash.
