Hey guys, I'm going to audition a CS Ultra tomorrow and will most likely buy it (it's only $400). It's being sold without an amp, so I was wondering if you have any suggestions on what to pick up? I know SVS packages it with a 1000-watt Samson, but it seems like I remember some people here not liking their product too much. Also I figure I can probably do better getting used gear. So any makes/models I should be looking for? Thanks!
