***Kelebihan:
1. Memakai chip DIODES Inc terbaru PAM8610
2. Memakai komponen SMD high precision resistor, dengan toleransi +/- 1%
3. Layout PCB multi layer dengan ground plane terpisah untuk memastikan S/N ratio yang tinggi, dan tingkat noise yang rendah.
4. PCB menggunakan material Fiberglass dengan ketebalan 1.6 mm, double-sided board.
5. Bahan PCB kualitas terbaik
8. Menggunakan capasitor power tipe Low impedance suara lebih dinamik.
9. Voltage controlled volume control. Pengaturan volume menggunakan tegangan, tidak perlu khawatir keausan potensio, noise dan gemeresek akibat potensio yang aus/ kotor tidak akan terdengar.
10. Menggunakan sealed potensiometer. Lebih tahan lama dan tidak mudah aus/kotor.
