I need some help. i'm currently rocking KLH 6's and been getting to thinking that they lack a little punch SOMETIMES. I've owned HPM-100s in the past and thought they were a tad bright. And now I've been offered a pair of JBL L80T3s for a good price. What do you guys think about the JBLs in comparison to the KLH and HPMs? I listen to a lot of rock, new and old, punk, some jazz and classical, hip hop. So i'm thinking that my speakers should be geared towards rock, no? Help!!!!!!!!!!!!
