I don't post here much so I guess that makes me a "lurker". I do alot of reading/following/learning through this forum, so I wanted to give a special thanks to the following guys who have supplied the DIY community with a magnitude of information and helped guide me personally: LTD02, lilmike, tuxedocivic, notnyt, BassThatHz, Erich H, diy speaker guy, Mfusick and of course many more. You guys make this hobby alot of fun and accessible without asking for anything in return. Thanks 
Well, about a year ago, I started looking into purchasing new amps for my home theater speakers. I've been using an Onkyo TX-NR818. Great receiver, but not quite enough power to get 7 speakers to references levels cleanly. In the past year, I've rotated in and out the following speakers: Curt's Sealed AviaTrix, Dayton Audio RS722, Clearwave Dynamic 4T SE and DIYSG Fusion Pure 10's. All great speakers, but the Pure 10's were real eye openers, especially for getting to movie reference levels with little to no distortion. So the current plan is to run 3 x DIYSG 1899(will be purchasing the kits once they're available) up front for LCR, and 4 x Pure 10's for surrounds.
At first I was settled on running iNuke6000DSP's for the mains and surrounds, but turns out they aren't so great for full range. Then I was going to buy Sanway LG clones, but they might not produce the best noise floor, especially on CD's/Waveguides. I eventually landed on Hypex amps. The new ncore amps would have been nice to try, but they were out of my price range. I started looking into the UcD amps and consistently found great reviews. Class D, efficient, clean, low noise floor and plenty of power on tap for 99dB sensitive speakers. Soooo I decided to put an amp together using 7 x Hypex's UcD400HG amps and 2 x SMPS1200 power supplies. This is my first attempt at building an amp, but with the Hypex boards, it should be pretty straight forward and "plug n play". Lucky for me, dad is an EE, so I'll have him look things over before I fire this thing up.
If anyone has any experience with these amps/power supplies or helpful tips in general, I'd be grateful to hear them. Through the build, hopefully this thread can put some good info out there on the interwebs too.
EDIT 8-11-15: Amp is complete. Final pics posted in post 2.
