Hi Space, I use a summing mixer, though not a Dangerous box. I know lots of folks around here aren't really fans of them, but I really like mine. My rig is an SSL X-Rack with 16 channels (fed off an Aurora 16) that sums and then goes to an SSL bus compressor and an SSL stereo eq. I can't speak to how the Dangerous box works, but I'm happy to help if you need a hand getting it set up to work in Sonar.
Regarding what you've been saying about addictions and just liking gear, I totally get what you're saying. Lots of folks have said that they can get the same results from various console emulation and saturation plugs, and honestly, I think they're probably right. Jeff and AT are good folks with good ears who seem to know what they're talking about and I have great respect for them and their opinions. That said, it's not really the point for me. I like the sound that I get out of it, I know how it works, I use it all the time, and I don't have to spend god-only-knows how long fiddling with plugins to get the sound that I want. Are there drawbacks? Sure. But I'm sitting in a room full of knobs and switches and dials and, warts and all, I still think they're kinda awesome and my clients seem to like it as well. For exactly the same reason that the room next to me is filled with real amps with speakers and knobs and pedals and cables, and when I go in there and plug in a guitar it's amazing. Sure, I own and use LOTS of plugins, and I have clients and deadlines and sometimes I don't use all that analog stuff, but I love it anyway. Even when it hums and crackles and is a pain in my ass. Different strokes and all.
Anywho, as far as I'm concerned, if you like that stuff and can afford it, get it and have a grand ol time turning knobs and cranking it up way to hot and distorting the crap out of it and sometimes finding that spot that is just freaking perfect. Let me know if I can help out.
