I'm afraid that's simply not true. a) Vista has no DirectX hardware support, period. That's why Creative falls flat on it's face. It uses OpenAL. b) The Asus has DirectX hardware support. In Vista, it uses the DS3D GX to translate DirectX hardware support to be the ONLY card that offers full surround sound and hardware support in Vista. c) It has the highest SNR of any card, 117 dB on all 8 channels, not just the front two... The X-Fi products, such as Creative and Auzentech, top out at 112 (and only on the front). To make matters even worse, the advertised X-Fi SNR is ONLY for output. Input is much lower, unlike the the Xonar. d) It has a sampling rate that destroys the competition. Creative X-Fi (and thus the Auzentech) is capped at 96kHz, the Asus hits a true 192kHz. e) The Auzentech is simply repackaged Creative X-Fi crappola, meaning it has the same hangups the X-Fi series has because Creative is the one that provided all the technology on it. Auzentech is merely an OEM that's licensed Creative's last ditch effort. Creative is going down the crapper because they dropped the ball with Vista. f) Just as Creative has no hardware support of any type in Vista, neither does the Auzentech. g) Asus uses Dolby Digital and DTS.. .Something the Creative and it's OEMs (like Auzentech) only drool about. hehe. If you want the ultimate audio.. Unfortunately the Creative and it's licensees (such as Auzentech) simply don't cut it. edit: Please bear in mind that my audio system that's hooked up to that computer is a Rotel preamp with Rotel power amplifiers bridged mono, Paradigm Reference Series Studio Monitor 100.2s, Yamaha sub and about $2000 worth of cabling.. Will you notice the finer differences between the soundcards on your Logitech speakers? Meh.. Probably not.
