This has been accurate in my testing. The noise floor varies depending on the frequency and usually, what I have seen is that the EMU's ADC noise floor is excellent from 100Hz to 10kHz ~-130dB with some noise susceptibility lower down and above. Less susceptible to noise as expected with the use of balanced cables and equipment. For example, no problem at all measuring the LSB of a 16-bit signal as demonstrated here: http://archimago.blogspot.ca/2013/07/measurements-dac-waveform-peeping-903db.html Easily measure below -96dB... I estimate that within the 20Hz-20kHz range, the EMU's limit is around -110dB with reasonable confidence. This is the level the Transporter and TEAC UD-501 measure using balanced interconnects. All the best with your testing Kellen! I encourage everyone with a decent ADC to give testing a try :-). Run a few experiments and find the answers for oneself and see if objective results correlate with subjective impression. Share your results with us - especially if you're hearing/seeing something surprising!
