Looking deeper however...the first 6db of attenuation shows just 0.1db of dynamic range lost, the next 6db shows 1db lost, the next 12db shows 6db lost. This is exactly the pattern I would expect to see. Where the DAC noise is so low compared to 16 bit quantisation noise, increasing the DAC noise doesn't impact much. As you go further down it starts to impact and then finally it accelerates. A Benchmark DAC1 would perform better. Looks like the Meridian DACs perform better too? To my mind the results show digital volume can be used in the right circumstances.
