Sound On Sound 不用介绍了吧？欧洲第一的高科技音乐录音杂志。
总的来说评价相当不错。优点中的第一条就是 Excellent audio quality（极好的音质）。
看优缺点和总评：
pros
Excellent audio quality.
192kHz capability.
Multi-client and Multi-Streaming drivers provide incredible versatility.
DirectWire features allow digital transfer form one application to another.
cons
You lose a pair of analogue inputs when using the digital input.
Music applications must be closed before latency is altered.
Serious S/PDIF bugs with version 3.80 drivers.
summary
With the four analogue inputs and eight outputs of the 192X, plus excellent audio quality and 192kHz capability, ESI Pro have carried on their tradition of being a little different, but where they really score is with their amazingly versatile E-WDM drivers.
