well to be honest, i wont be upgrading my rig until i get hired somewhere, and that wont start until august. but for 150 bucks or so, that aint a bad way to go. and to be honest, i was thinking about that ad-20 for my csbs. the signal is soooo low on them that at isis i had to boost the wav form by 20db after i dumped it off the jukebox, whereas the CMC-8s got a tad bit of that fuzziness i encoutnered at manson earlier this week.
