Elite Bastards posted an Auzentech X-Meridian 7.1 sound card review

Although there are several boards floating around that make use of a reference design based around the CMI8788, of which the b-Enspirer is one, Auzentech have eschewed simply creating another clone of that particular design. Instead, their team of engineers, experts in both digital and analogue audio, have set about creating their own board design around the Oxygen HD core, with the emphasis of their efforts squarely focused on sound quality. While most reference-based designs use only a single-layer PCB, Auzentech have opted for a dual-layer design, due to the larger number of components used on the X-Meridian. Auzentech argues that these additional components, when used correctly and of a suitable high quality, are required to enhance the analogue signal as it travels from the CMI8788 chip to your speakers, and prevent the normal degradation seen as sound travels along a circuit.
