Ta płytka wzmacniacza ZK-AS21 jest niesamowita! Jakość dźwięku jest wyjątkowa, a instalacja była bardzo prosta. Bas jest mocny i czysty—jestem bardzo zadowolony z zakupu!

I’ve been using this Creatall AS21 amplifier for my home theater setup for a month, and it’s been fantastic! The build quality is top-notch—metal construction feels durable and premium. The TPA3255 chip delivers crisp highs, balanced mids, and deep, punchy bass that fills the room without distortion. Bluetooth 5.1 pairs quickly with my phone and smart TV, and the connection stays solid even through walls. I appreciate the multiple input options (AUX/USB/Bluetooth) that let me switch between devices easily. The protection features (overheat, short circuit) give me peace of mind for long-term use. The company’s customer service was responsive when I had questions about wiring, and the sample delivery was fast (arrived in 7 days as promised). For the price, it’s way better than some expensive brands I’ve tried—highly recommend for anyone looking for a reliable, high-performance amplifier!

Das Creall HT21 Verstärkerboard hat meine Erwartungen übertroffen! Der Bass ist tief und klar, und es ist super einfach zu montieren. Absolute Empfehlung für alle DIY-Audio-Fans!
