I just built 2 of the Hypex DIYclassD mono kits.  They work perfectly.  $1050 shipped CONUS

Used for 30 mins.  They were $675 each delivered.  They seem to be out of stock now. 
The only liberty I took in building them is that I sanded the surfaces down a little on the inside and put thermal grease between the amp and the chassis. 

Here is the detail:  https://www.diyclassd.com/product/nc400-mono-kit-complete-kit/24

I'm selling because right now I need more channels for the Linkwitz affliction. 

This price is firm.  I think it is a good deal.  I wish somebody had made this offer when I bought them. 
I am not the haggling type.  If you don't want them at this price, please move on. 

Thanks,

Alan
