Product details

Hypex NC400 1x400W Ncore Monoblock Kit


The NC400’s audio performance sets new standards, regardless of operating class or circuit technology. Thanks to the Ncore technology it does not only offer a way for audiophile music reproduction to continue in an ever more energy conscious world, its measured and sonic performance actually raises the bar for audio amplifiers of any description. Building on the strong heritage of UcD, Ncore takes the things UcD does well and does them ten times better. Literally. Distortion (THD and IMD) over the full audio and power range is negligible, typically below 0.0007%. Distortion at listening levels (1W) is unmeasurable. This amp adds neither dirt nor fairy dust.


This kit includes everything you need to assemble a powerful high-quality monoblock amplifier.



  • Transparent, fully discrete input circuitry
  • Differential input with high common-mode impedance
  • Overcurrent protection
  • Supply overvoltage/undervoltage protection on all rails
  • Full aluminum case with predrilled mounting and connection holes

Specifications for: NC400 1x400W Ncore Monoblock Kit

  • Rated power output (RMS) The electrical power measured in watts (W) that an amplifier can output per channel, without damaging the amplifier or the output signal is çlipped'. RMS = Root Mean Square.

    1 x 580 watts at 2 ohms

    1 x 400 watts at 4 ohms

    1 x 200 watts at 8 ohms

  • Bridged power output (RMS) The electrical power expressed in watts (W) that an amplifier can output per bridged channel (2 x stereo to 1 x mono output), without damaging the amplifier or the output signal is çlipped'. RMS = Root Mean Squeare. -
  • Minimum load Shows the minimum load that an amplifier can control in ohms. A lower impedance of a speaker is not recommended if it is lower than the minimum impedance of an amplifier. An amplifier works best when the impedance of the speaker falss within the impedance range that the amplifier prescribes (for example, 4 to 8 ohms). 2 ohms
  • Signal-to-noise ratio (SNR) Shows the strength level of signal power compares to a level of noise power. Generally, higher values ​​means better specification. 125 dB

    The best choice (quality/price) for a class D amp

    Dit is een geweldig product! Deze klasse D versterker is serieuze concurrentie voor top klasse A versterkers en daarbij zeer zuinig en licht.
    Het laag en de detaillering hiervan is met name zeer goed: een zeer "strakke" basweergave. Bovendien is de dynamiek geweldig, waardoor je het idee hebt dat je naast het podium staat..
    Een aanrader!

    Kingt absolut neutral und dennoch kein bisschen langweilig. Hatte vorher ein 30 (!) mal so teures Röhrensystem; der NC400 sollte eigentlich nur zur Überbrückung für ein paar Monate bleiben - jetzt darf er langfrisig bei mir arbeiten.

    The amplifiers are fantastic! There is so little distortion that they are a perfect studio monitor amplifier. SoundImports were great to deal with: excellent communications and quick shipping. These are kits yet require no soldering, just basic hand tools. I'm happy to have discovered this company! Thanks, Graemme

    5 / 5

    Easy to build.
    Soundwise there is no sound I would say. They do really well with the Dynaudio Contour 30.
    Came from NAD C375 (which is good already).
    The NC400 have a much bigger stage and deeper room. Bass is slightly more tight.

    5 / 5

    Compared to my old AB amps the NC400 are much faster and more detailed soundstage. I hear new details everyday vhen listening to my old platters(cd's).
    I cannot say that I have heard anything better and then you have to realize that I have been principle serviceman for Krell and Audio Research so I have some reference experience.

    Easy and fun to assemble, and soundvise it could make some overrated American heavyweights to be very nervous.
    Heartly recommended

    5 / 5

    - Very high surface / build quality
    - sturdy and high quality binding posts
    - neutrik XLR
    - no soldering required
    - very clean and controlled sound
    - beats much bigger class A amps easily
    - runs quite warm for class D

    - Aussergewöhnliche gute Verarbeitungsqualität des Gehäuses, sehr edele Oberfläche
    - kein Löten erforderlich, nur schrauben und stecken
    - hervorragender, neutraler klang mit jeder Menge "Druck"
