I say 'marketing monster 'as you will never see 108dB SNR in your computer. There is also some question as to whether the DSP used in the Audigy series will ever be truly a 24 bit solution. It's a fact that the emu10k01 is a 16 bit machine and needs to upsample or downsample to do its magic. You can read more over at digit-life. It's a fairly damning article.
