The Power Supply Battle: Switch-Mode vs. Toroidal

Exploring Whether Power Supply Type Affects Audio Quality  Among audio enthusiasts, there’s a common belief that switching power supplies are unsuitable for use in high-quality audio equipment. But is that really the case? Let’s find out! We’ll take a single amplifier and power it first with a switching power supply, then with a “classic” toroidal transformer. We’ll measure sound quality parameters — including distortion levels and output power — and draw some conclusions.... Read >>>

SCIBER AMPLOI Hi-End Amplifier: Review & Test

In today’s world of audio technology, it’s no easy task to impress seasoned listeners. And when we at SCIBER entered this field, we had no intention of creating “just another amplifier.” Our goal was to develop a device that would stand head and shoulders above others in its price category. We started from scratch and worked through dozens of circuit design iterations. We paid great attention to industrial design, protective circuitry, and — most importantly — sound qualit... Read >>>

Filter method for measuring the harmonic distortion coefficient

This article discusses the measurement of such a parameter of audio path components as the Total Harmonic Distortion (THD), with a sensitivity that goes beyond the capabilities of any commercially available ADCs/DACs. Basic Terms Harmonic distortion is a type of nonlinear distortion measured with a single-tone input signal.Nonlinear distortion is the appearance of harmonic components (integer multiples of the fundamental frequency) in the output signal spectrum t...
