I dont' know too much about audio equipment so all that dolby, surround sound, 5.1 6.1 is all jargon to me. How does a DSP (digital signal processor?) work in relation to getting the sound from a DVD to the speakers? I want to get this(SoundBlaster Extigy) Hook-up to your PC or notebook with the hassle-free external USB connection Experience high-definition audio with 24-bit multi-channel performance with 100dB SNR clarity Transform your PC into a home-theater system with Dolby Digital 5.1 surround sound Enrich your listening experience with innovative EAX ADVANCED HD music enhancement tools It has all that which sounds great to me, so is it ? I've also read some stuff about most high-end video cards have dvd decoding chips that make movies better but I've always thought it was the DVD-ROM that made the difference. So any of you home theatre freaks think this Extigy unit lives up to it's claim? http://www.soundblaster.com/reviews/ All these are gaming and PC hardware publications, I find reviews from 'pure' audio experts abit more reassuring.
