The Alpine unit does do a lot of very good bass 'equalisation' which really gives a much fuller and flatter response.

With regards to the time alignment, the human brain can easily percieve differences as small as 0.1ms between left and right sides of a car. Try this: Play your home system at a reasonable level with some female vocal thats got a good center image. Standing in the middle, listen. Then move to one side. I bet even 1ft or 2ft movement totally flattens the soundstage. This is to do with the time delay and path difference. With a time alignment circuit, you can compensate for an off center seating position as in a car (unless you're lucky enough to own a McLaren F1!!), and still generate a fantastic center image (right above the central air vents!).

Anyway, find a dealer with a PXA600, or try to go to an IASCA event (www.iasca.com) and listen to one in a competition car.
