Magnat High-End High Current Amplifier
Speaker produce sound based on electromagnetism. Here are just two important factors. A high power magnet and the current going through the coil. High current means fast moving membranes means vivid Hi-Fi sound. But current means thick cupper cable and amplifier with low voltage power stages that are all costly to produce.
The cheap an easy way is to use audio equipment with high voltage output and low amp. On the paper these products have sufficient Watts. Because Watt is calculated by Volt * Ampere. High Watts does not say anything about good audio. Low current always results in weak audio.
More reliable is to see the size of the wiring. If the wiring is very thin the audio quality must be week, because low ampere means week audio without exemption. Most of the smart Home Audio products using even network cable to power speakers. No need to say what kind of sound quality you can receive.
High-End Audio does not need to be expensive. Over the last forty year, especially one German company has proven this. Magnat offers upper High-End Audio products at reasonable pricing.
