Class D amplifiers are getting better and better. Where we got serious(er) performance with UcD, the step to nCore was already extremely big. Eigentakt is another serious step toward fine high-efficiency hi-fi. Now it’s the turn of Hypex Nilai. We are building the Nilai 500 DIY kit for you, so you can see that you can assemble and beautiful power amplifier within an hour. You can expect the full review soon.
Last week I added a second PSU turning it into a dual mono amp with double the power into 4 ohms. I disassembled the amp, drilled 14 new PSU mounting holes and five large holes to fit some metal Temu air vents into the base plate.
The additional PSU was supplied with two amplifier connection cables (not required), a power input cable and a 12 pin auxiliaries cable (J5). I soldered the power input cable to daisy chain it with the original power input cable.
I also soldered five wires on the 12 pin auxiliaries cable to the original 12 pin cable. This required carefully removing some of the insulation from the original cable, soldering the ends of the new cable onto the original cable and then insulating with electrical tape. The five wires I connected were:
Pin 2: Ground
Pin 7: Pushbutton+
Pin 8: Pushbutton-
Pin 9: Trigger+/-
Pin 10: Trigger +/-
The end result sounds slightly better than with a single PSU IMO. The extra headroom seems to have given the bass better control and more weight behind it and added to the overall clarity at louder volumes.
Nice. Well done and have fun!
Good job, but I would have just gotten the monoblocks
beste lezer(es),
Heeft iemand ervaring met het inbouwen van de Hypex Nilai 500 monoblock(s) in een Ghent audio behuizing?
No, sorry. No experience with that. But that can’t be realy hard? Maybe mod the cables a bit. But the Nilai DIY kit is a complete kit with a casing… Why use a different case?
