They are excellent HUs, but I doubt anyone could tell the difference between it or any other top quality HUs. It is one of the better looking HUs I've seen though.
Actually for the price it's probably the best out there! Alpine CDA-7990 is probably the closest competitor. However the Alpine has more "features" and a heftier price tag.
I will say this though, unless you listen to music that actually would benefit from this type of unit, just grab a decent affordable one.
No need to pump the latest shady track on this puppy when all you care about is booming bass line.
