Bij Sharky Extreme is een review online gekegeld van de Diamond Monster Sound MX400 gebaseerd op de Canyon 3DTM audio controller van ESS. Deze soundcard heeft verder een digitale S/PDIF interface, quad speaker support en biedt ondersteuning voor EAX 1.0, EAX 2.0 en A3D 1.0. Hieronder een hap uit de conclusie:
Judging by our experiences with the MX400, it appears as though the card is targeted at a slightly different market than competing offerings from Creative Labs and Aureal. Lacking the more advanced gaming realism of the SQ2500 and coming up short in sound quality to the Live! series, the MX400 seems most adept in the overall value it provides. With most of the competition taking place in the high-end performance gaming sector, there is definitely room for a value-oriented card offering excellent positional audio and a few extra features (coax-out and RioPC connectivity).
A few aspects of the card left us desiring a little something more, such as the options for internal connectivity. A stereo AUX output would be very useful, as well as an S/PDIF connection. In addition, sound quality from the MX400 was noticeably bright, a quality attributed to the Canyon3D processor.
