Amplifier & Preamp

Amplifier & Preamp


NuPrime Reference Series and Class A+D hybrid Series Power amplifier, Preamp, Integrated DAC amplifier.


Hybrid Class-D Amplifier Design With Different Sonic Characteristics

Class-D Amplifier designs can implement switching frequencies at more than 500kHz (CD is 44.1kHz). In our lab, we have designs running at 1MHz with vanishingly low THD at broad ranges of frequencies and power with commendably low jitter. Without belaboring the reader with mind-numbing details, our engineers can now produce class-D amplification that, as we say, lies close to perfection. We’re not suggesting that most engineers know how to accomplish this. The market is crowded with poor implementations of Class-D technology.
