RMAA: Audient iD4 24-bit

August 19, 2016 ohm

Adjusting input levels, and volume is easy breezy thanks to fine-tuned DAW and plug-in controls. Its headphone amp being poorly suited to low-resistance earphones, returning anomalies in frequency response, THD, IMD, and stereo crosstalk. Most of the anomalies smooth out by the time portable or monitoring headphones are plugged in. And, iD4 spits perfectly matched volume into both channels at all volume levels, not to mention trace amounts of background noise. I’ve yet to go deep into its microphone amps, but after digitising test signals from Mojo, I am relatively convinced of its recording fidelity - considering its price, and ostensible market. Stereo crosstalk numbers aside, that is.

June 11, 2015 ohm

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.
