SMSL SH-6 Desktop Headphone Amplifier

Advanced R-2R chip Audio DAC

A desktop mini headphone amplifier with incredible output power.

• Every detail is high-end design.
• 4 pieces of legendary R-2R chip PCM1704U-J from BB, 2 pieces per channel, fully balanced design, maximize chip performance!
• USB uses XMOS second generation 16 core processor XU216, supports native DSD512 and 32-bit 768kHz!
• Top digital filter chip SM5847.
• The clock system uses two accusilicon ultra-low phase noise crystal oscillators.
• Using Altera's high-speed CPLD to process the clock and reduce jitter.
• Support LVDS level I2S transmission (using HDMI interface), can transmit digital audio with the lowest jitter!
• Built in low clock jitter VCXO and PLL, support access to external clock!
• Full function remote control with color LCD and newly developed user interface.
• Use 7 OPA1612 top OP-AMPs from TI.
• High precision, low temperature drift, resistor and capacitor are widely used.
• Low noise discrete component power supply circuit.
• Customized low-noise sealed toroidal transformer manufactured by Noratel, UK;
• All aluminum alloy CNC shell, separate power supply and motherboard design, effectively isolate power interference.

Features
