ok, my amp is dying quickly and i need to at least start checking out new amps. right now i have a combo but i'm looking to find a nice head and cabinet in the future. i've looked at reviews on the eden, swr goliath, and several others but i dont have much expirience with what all the amps sound like and whats best for my kind of music. i play heavier stuff, ummm like, mudvayne, slipknot, system of a down, etc, etc.....what is the best amp for tone and durability. i know i've posted something like this before and i was told to check out the eden nemisis. i just want to make sure i've got several opinions before i make an investment on something like this. i appreciate all the help.
