Technical guides on acoustics and sound, explained step by step: how your gear works, how to improve your room and get the most out of it.
The design of Hi-Fi audio cables combines engineering principles with artisanal craftsmanship; although they may appear to be simple conductors on the outside, behind the scenes there are technical decisions regarding materials, geometry, and assembly that aim to preserve the signal from the source to the speaker. Manufacturers examine electrical variables—resistance, capacitance, and inductance—and mechanical
The audible difference between a €1,000 digital-to-analog converter (DAC) and one that costs €20,000 is nowhere near a difference of €19,000. Modern conversion chips—even those found in mid-range equipment—already operate at the theoretical limits of human perception. So where does that astronomical cost come from? It is a convergence of cutting-edge engineering, luxurious materials, and
Unlike semiconductor designs, tube amplifiers cannot drive speakers without an output transformer. Vacuum tubes operate with plate resistances measured in the thousands of ohms; speakers, on the other hand, have impedances in the range of a few ohms. Connecting the two directly would prevent power from being transferred efficiently, and the signal would suffer serious
From the dawn of postwar electronics, two components emerged as cornerstones in the design of audio amplifiers: the 12AX7 and 12AU7 double-triode vacuum tubes. These small glass cylinders, with their nine pins and orange glow, became the sonic heart of countless guitar amplifiers and hi-fi systems. Their development by giants like RCA and GE was
