Music is made up of two parts: content and sound. When you play a piece of music on substandard equipment, you do not get to enjoy the entire ensemble. And when you don’t listen to music in its whole sonic glory, you’re missing half of it. Despite many Hi-Fi components have built-in headphone amps, they do not do musical recordings the justice they deserve. However, I am confident your music experience will change within seconds of plugging in your headphones into any of the Erzetich headphone amplifiers. Essentially, your headphones are the same as your stereo speakers and to produce the richest sounds - thick bass, clear sound, less distortion, good soundstage etc – they need an amp. The headphone amplifiers I make are fitted with a double voltage power supply and a high quality input capacitor in the signal path in order to deliver a clear, unimpeded sound.
