As I understand it, the higher power handling of my EVMs and G12K-100s (and V30s, etc for that matter) means no speaker breakup. Personally, I like this. I'm not after a chimey sweet vintage sound, I'm after a tight and brutal modern sound, and that mainly comes from my preamp distortion. That means I'm not after power stage distortion, and definitely not speaker breakup, even though these things are absolultely essential for other types of music, of course!
That's why I think something like the EVM12L-Black Label matched up with G12K-100s is more towards what MDV is asking for - good reproduction of the already fairly processed signal, with extremely tight response throughout the frequency spectrum. Oh, and that beautiful, beautiful grind of the G12Ks...
The mixture is fantastic, both clean and at high gain - really fills the room and makes you feel all warm and damp, if you know what I mean :)
