I have the 8033C that I use with an SVS SB12-NSD, and find that it does as prescribed. I, too, wouldn't go without it. At first, I wasn't certain I needed it and tried selling it. When I got no takers, I kept it...and am quite glad I did in hindsight. I switch so that I can listen without it every so often on certain tracks, and now realize what it brings to the table. I have commented about it on this forum before; it really does what it's being sold as. No matter what I listen to, everything (bass) sounds, well, near-astonishing. I cannot locate where the sub is (which was ALWAYS an issue in the past, no matter what sub I used) in the least; and following bass lines or lower piano registers can be an extremely fun and rewarding experience. It's also nice that it is literally a set-it-and-forget-it unit. I'd recommend to anyone (also, I think there's one being sold on A'Gon right now...that is, if you dare go there anymore). And yes, the mic comes with when you purchase it.
