I have the LT-TB version of the Lynx Studio HILO ADC/DAC (~3000$) in office for another week, in which time I will continue to evaluate it as a pre-amp, a DAC, a headphone amp, as well as an ADC. My full review of it will be published at Headfonia. While I've not had time to formulate hard opinions on its DAC sound quality, I can say this: its ADC is as good as it gets this side of an audio analyser. Below are 16 and 24 bit / 44kHz RMAA test results for both its line and headphone outputs.
