I compared the ZM-RSSC to a Yamaha DSP-A1 5.1 Amplifier?s internal DSP chip. As I used the A1?s line in amplification for the ZM-RSSC tests the onus was definitely on the processing chips with both sound solutions outputting to my Mission Cinema 7 speaker setup. For gaming I compared the ZM-RSSC to a Soundblaster 5.1 Live and the onboard 5.1 sound of the DFI Lanparty 865PE.
The results were good. Movie?wise The ZM-RSSC copes well with everything you throw at it, only showing weaknesses when compared to the Yamaha amplifier (to be expected at 32 times the price!). In Games, compared to the onboard and the 5.1 Live!, the ZM-RSSC was quite competent. The 5.1 Live! was a little bit more controlled with tighter bass and had clearer treble. The onboard was identical to the external card.
Is it worth buying? Read on...
