Raspberry PI , RPI I2S DAC Measurements.

To evaluate the performance of various DACs and AMPs we decided to  measure them. Our Measurements are not extremely accurate,but accurate enough to give us relative performance numbers in our setup so that we could make an informed decision. We knew the manufactures had provided the numbers but we wanted to ensure that we chose the right combination for our player.
