Which metal CD would you use to...

Kamelot-Black Halo
or Dream Theater-Images and words

The production value is very high so it will be easy to tell if its distorted and theirs a lot of different instrumental ranges.
Low quality production black metal or Death metal with growls won't be useful at all and Heaven Shall burn sucks

This.
Although it would be useful to see how the speakers handle low quality production stuff.
