The original NanoSound DAC is one of the most successful Pi Audio Products launched via Kickstarter, with 274 very satisfied backers and delivered on time. NanoSound DAC is a Raspberry Pi Add-on Board with HIFI DAC, LDO Voltage Regulator, OLED Display, Power Switch, Control Buttons and Infrared Remote.
2 x ultra precise crystal acting as master clock for lower jitter and better DSD performance. They provides very accurate timing for 44.1khz and 48khz respectively, resulting in less jitter and better sound quality. It also let the Raspberry Pi to do less work by not requiring it to generate clock signal, hence less heat and better playback performance for CPU intensive playback like DSD.
Improved and wider sound signal paths
Critical electronics component uses top audio grade capacitors by ELNA, WIMA, EVOX instead of much smaller and cheaper surface mount counterparts
*NEW* for NanoSound DAC 2s
2 Oz Copper PCB Manufacturing for better heat discipation and lower resistance
