Summary: Good quality and good design. You will never regret with the sound of this card. I have used X-fi, Auzentech, Audiotrack but I could only compare Auzentech Prelude to this Asus Xonar D2. Just because these cards have the same quality.
Summary: Absolutely fantastic sound, and of the five PC's I have used these cards in, not one problem yet. One word of advice is that if you intend to use headphones, I would get the ST or STX because of the greater number of headphone impedance matchings. The quality of build and packaging leaves Creative for dead, frankly.
Summary: Asus sound cards really are amazing, and this one is no exception. Sound is great. Not quiet as good as the ST or STX, but still very good indeed. Finishing and presentation are absolutely superb. Despite what the previous reviewer said, I have had no trouble at all with the cards or drivers. They are rock solid.
Summary: If you are considering this card for headphones; don't! Get the ST or STX instead. This card will happily drive headphones, but the ST and STX have a wider range of selectable output powers for different headphones. The card also sounds a little brighter and lighter than the ST and STX, which in my opinion is not as good for headphones.
Summary: Finally decided to ditch my x-fi ExtermeMusic after a year of tearing my hair out with Vista x64. Arrived this a.m and haven't stopped smiling since. Music playback is crystal clear and punchy, I've finally got my subwoofer back under media centre so movie watching is a joy. To top it all off I loaded up Crysis and ...WOW!!!
Summary: Got thsi item today after putting up with snp, crackle and pop, skips and jumps of creative bloatware under vista x64 and i have to say it is brilliant.
I'm runnung a Dell XPS 720 with 8gb of ram and vista ultimate x64, the install went without a hitch, and finally have propper sound.
Summary: Bought this replacing a X-Fi (as many people have)It was a cross-up between this and the Auzentech Prelude, and I'm very happy with my desicion! This is easily the best sound I've ever heard coming out of a home system! running it to 2x 130 watt studio speakers (M-Audio BX8a) and the sound is crystal clear. Good software, although the Music preset has far too much reverb and sounds somewhat crap, the 'Hi-Fi' mode actually seems to sound best for music.
Summary: Just got this on impulse on a visit to the Overclockers outlet. It has replaced a SB Titanium Fatality pci-ex card. What a difference - awesome sound - really impressive. Never going back to Creative - no popping or crackling, well happy.
Summary: I recieved mine today, hurriedly ripped out (not literally) my X-FI Xtreme Gamer and replaced it with this, obviously havign removed any trace of Cretive drivers or software from my computer before..
All I can say is..WOW, the speaker position ester alone is better than my X-FI sound experience as a whole. Nor mroe screams of death, cracking or popping. Just amazing sound quality from a fantastic product!
