Hypex NCore® technology

Ncore® is the first Class-D amplifier not just to nudge the best linear amplifiers, but to surpass them in every aspect relevant to sound quality. If you want the ultimate in clarity, resolution and musicality, there is no longer a reason to trade efficiency or compactness.

NCore technology combines the stability of UcD with improved load-independence, lower distortion and lower output impedance.

The approach is multi-pronged:NCore |Tech

  • A mathematically exact understanding of selfoscillation. This allows optimization of largesignal performance. 
  • Improved comparator circuitry insures that actual behaviour matches the theoretical model as closely as possible. 
  • New gate drive circuitry improves open-loop distortion at moderate signal levels while significantly reducing idle losses. 
  • A new control loop ups loop gain by 20dB across the full audio range without sacrificing stability.



Amplifiers using all four of the above will be Ncore. Amplifiers using only the first three will be sold under the UcD brand even though their internals no longer resemble that of the well-known 2001 circuit
