Probably more of a personal taste thing. To say one has better sound quality than the other is pretty far fetched when comparing quality equipment.
Anyone that tells you they can tell a difference, IMO is full of BS. This day and age, pretty much any quality amp will be completely colorless when being used within its limitations. Whe I hear people say that this amp is "warm sounding", or "robust" I'd like to poke them in the eye with a stick!!!!
Before the flamers kick in, were not comparing a high end amp to a boss audio amp from walmart. Thats for another discussion.
All being said, I would opt for the ZED not only for the appearance, but as previously mentioned, better processing options, and more power. well worth the extra $$ (not to mention it is a 6 channel, and the jl is a 5)
IMO JL audio makes some great subs, and some darn good amps, I just think there are similar options out there for far less $$$.
Kinda like sunglasses. I will not pay $150 for a pair just because it says oakley on the side. I can get a pair that do the exact same thing for $30.
but thats just me.
