Sujet Aux possesseurs de l'ESI Waveterminal 192 :

Citation : Total harmonic distortion didn't rise above a good 0.004 percent at any sample rate, but background noise results were disappointing, and also varied by up to 5dBs depending which inputs and outputs I used. At 24-bit/44.1kHz the best result I got was a reasonable -93dB RMS (about -95dbA), while at 96kHz the noise levels shot to a very poor -85db RMS. Even worse were the stereo crosstalk measurements, which at around -54dB were the highest I've ever measured. This means that significant amounts of the left channel leak into the right and vice versa, and is perhaps due to poor screening in the umbilical. They ought to be -93dB or lower, although this probably won't worry too many users at this price point. At first I thought I might have received a damaged or poorly built example, but I later discovered almost identical RMAA results posted on the Internet from a user's 192M. I don't understand why the noise levels at 24-bit/96kHz are significantly higher than at the other sample rates.
