100% brand new and high quality. Using original TPA3116 and CSR4.0 Bluetooth module
Coupling capacitance by Germany's Siemens 1UF. Signal main circuit electrolytic capacitors used in Taiwan brand, the main filter capacitor electrolytic capacitors imported from Japan to ensure strong support for a steady stream of power.
Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio.PCB using 1.6mm thick double-sided sheet, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. PCB-class quality.
Fully enclosed dust-proof potentiometer, the performance is more stable, more durable than ordinary potentiometer!All-shielded audio-specific high-current inductors, to ensure crisp and powerful sound.
