Hybrid Audio is one you mentioned. but what are the others? if like me i go with what is sold in my town, i want my hands on them, able to run back up to the shop i purchased them from if a problem happens. ect. Are the companys your talking about online order only? i've ran alot of different componets and in stock locations infinity kapa perfect has had the best sound to my ears. i just bought a set of street edge and i must say i hate them. they seem to be muffled or something. Ive tried every setting in eq and still can't seem to hear what i should be able to.
