  I don't think I missed anything, so that should be about it. I already had the glue, stain, Deft and tools to complete the project which was pretty great. Not to mention free wood so for any of your projects factor those things in. For those of you asking about the crossovers and those component they are included in the Parts Express kit along with detailed instructions. The total came to $395.34 but I had some materials left over for use on future projects so I would actually say its a little less. Additionally, I found the SMSL Q5 on sale from Parts Express so it came out to only $84.00 so that cut costs a lot I just couldn't find a link with that price, this build happened about a month ago.

Yep. Ok, so all joking aside, your hinge ideas seem fine, if you go the route of replacement, just make sure the screw hole distance is the same and the spacing and diameter of the hole in the door is the same that you're replacing. From the pictures in your OP it look doable. Another option could be, putting a strip of high density foam tape around the three sides of the cabinet doors that aren't the hinge side. This is basic door weatherstripping stuff that will easily muffle the sound of them closing much more than the bumpers, be a lot cheaper than new hinges or dampeners, but on the down side, might look iffy. You can research around and find this stuff in most basic colors, at least natural common tones like white, black, beige, etc.
