I beg to differ honey,
Tried the jbl (gto i think) and the mutant sounds much better, in my opinion obviously.
Have to admit i'm not sure what the shop prices are as i get them discounted via a trade supplier, but i think i only paid about £40 so they can't be that expensive retail, are they?
But at the end of the day, we can buy whatever bits we like, but it's how well we install them that will make the biggest difference.
