i have expience with MA Audio amps.. ad i think they got better..
i have experience with the old models and ow the new ones.. now, i have tried the Mi series, which is the lowest class amps, and they're good...
but i think there's better out there for the money (retail prie).. depends how cheap can you get them... the only reason i bought the mi amp is because i got them dirt cheap.. i tried them and sold it double the price =)
if you want me to compare them to jbl amps, i'll choose MA Audio over jbl..
(i know i'll get all the hate now, because everyone here is soo inlove with jbl amp)
hope my input helps you out..
