These new amp modules (plus power supply) are the latest and simply the best class D amps I have ever heard.  They simply sound like music.  The NC-400 is only available for DIY so you will not see any finished products using this amp module.  You can buy the amp modules and power supplies directly from Hypex/Holland and assemble them in your own case or have someone else build it for you.   We can build the amps for you and also mod the modules for even better sound.  Check out this link for the latest info:
