How to DIY yourself very nice Class D monoblocks


If you want to know what the hoopla is about Class D and want to put together a very nice sounding kit I have a starter recommendation for you.

Go to Parts Express and search for "ICEPower ASP"
Next, look online for Ghent Audio. They make many sets of cases.

You'll need a high power soldering iron, and screw skills.
Between those two, you can put together a very nice monoblock for around $500 a piece.

I highly recommend both. I have no financial interest in either. 
You may need wiring kits, so make sure to order appropriately.

What are you guys doing to get around the low input impedance of the ASP modules? I think it’s around 7-8K ohms. My preamp’s output impedance is 200 ohms. That's not good, right?
Thanks, george and erik.
Let's say you wanted to build two mono amps with NC400 modules, but you wanted to put two NC400 modules in each mono chassis so one would drive the bass panel and the other would drive the midrange/tweeter.  Is it possible to split the input at the mono amp so the signal goes to both NC400 modules?  Are there any possible downsides in doing so?
I’m not really interested in active biamping yet. I just learned that the NC400 modules are bridgeable, so it’s possible to use two modules per channel and have double the power. Would the input impedance of two bridged modules also have an input impedance of 4k ohms?
Do the NC400 Hypex kits come with two mono amps or do you have to buy two at € 650 for stereo?

The latest Icepower modules (IceEdge 1200AS1 and AS2) are not sold directly to end users but to OEMs only. They are way, way better sounding than any other Icepower module......and even better than Ncore NC400 and NC500 modules.

Which exact amplifiers have you compared to come to this conclusion?
Sorry, George, I was comparing similar amps to each other.  What you linked to is not even close and then you mentioned something that doesn't even exist yet. 
Check out this Nord amp.  It is the exact same price in USD as the Hypex NC400 kit, but it comes with the NC500 module, an input buffer, a bigger power supply, and it's already assembled.

If you buy the stereo version, it's actually cheaper than two Hypex mono kits.
