Technical guides

When a sound system doesn't perform as it should and the music sounds "muddy" or congested, many people blame the original recording or harmonic distortion. However, the culprit is often a more technical and unpleasant phenomenon: intermodulation (IM). This problem arises when different audio frequencies, instead of coexisting peacefully, collide within an audio system. This

The thinnest TVs on the market compromise audio quality. Teufel explains why this happens and what solutions are available to restore the sound you deserve.

I spent money on a good soundbar, but it turned out the furniture was the reason for the poor sound quality. I’ll explain what’s physically going on and how to fix it without spending a dime.

There was a time when a good Hi-Fi system was the go-to choice for anyone who wanted to enjoy great music at home. But its popularity gradually declined as Bluetooth speakers, wireless headphones, and soundbars emerged, making it seem almost like a relic of the past. Some people even classify them as part of the

Today we’re going to get a little more technical in our explanation of the cathode follower, but without going overboard, so that any audio enthusiast can understand it. How the Cathode Follower Works This is an essential stage in vacuum tube amplifier circuits that, far from increasing the voltage, is designed to provide a stable

Setting up a home theater is an exciting project. Choosing the front speakers, tuning the subwoofer to deliver precise bass, and configuring the AV receiver all become part of a ritual. However, behind that home theater lies a monumental amount of cables. Connecting the receiver to the speakers, subwoofer, console, computer, and display can turn

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
