Class D or FirsWatt/Aleph

Started on the box for F5
 
Looks neat. I am sure you have already figured this out but if you build the power supply to the standard specs outlined in the F5, F6 M2 etc threads, you should be able to swap amplifier boards on the heatsinks. Probably the biggest benefits of making FW clones.

I believe you can get the UMS measurements, drill and taps most or all the holes while you have the tooling out. I figured the F5 may be a good choice for electronic type of music as it is supposed to be very detailed which can make those synthesized sounds really cool.

Sparkle, It looks like you have opted for a class A build but I will offer my take on D vs A etc... I recently built Nelson's ACA Mini to replace a small Class D Topping amp in my office. The difference was not subtle. The D sounded dry and constricted, one dimensional, compared to the little Class A. The ACA Mini sounded more spacious and musical. I will never return to the Topping for my office rig.

But not all class D amps are the same. I used some ICEPower 200 ASC modules in my main rig for a while. I later built amps based on the 300 ASC modules. The amp modules are identical in size and connections but sound different, almost like the difference between the Mini ACA and the Topping. Almost. The 200 ASC sounds relatively 'harsh' in comparison to the 300 ASC. It sounds more open and natural yet not to the degree of the ACA Mini but still very pleasant and listenable.

So is A better than D? As a rule, I think so when A is done right. But it depends on the amplifiers. Not all D is truly 'bad' and my own experience showed me that. But it also showed me that the A I tried yielded a more pleasant listening experience than three different D's. YMMV.

And good luck with your build. It's looking good!!
