The ASUS Xonar DX is a PCI-E sound card with a 116 dB Signal-to-Noise Ratio (SNR), which provides audio that is 35 times cleaner than onboard audio. With the support of Dolby technologies and GX2.5, the Xonar DX provides rich audio effects in games and theater quality audio in movies.

Dolby is globally recognized for their innovations in audio for cinemas, home theaters, PCs, and games. With Dolby technologies, your PC is upgraded to surround sound and transformed into an immersive digital entertainment center. These include Dolby Digital Live (Real-time 5.1 Dolby Digital surround sound encoding), Dolby Pro-Logic IIx (Converts stereo or 5.1 sounds to a seamless 7.1 surround sound field), Dolby Headphone (Delivers a realistic and spacious 2-to-5.1 surround or 3D positional sound field over any set of stereo headphones), and Dolby Virtual Speaker which simulates a highly realistic 5.1 speaker surround sound listening environment from as few as 2 speakers.

ASUS designed GX2.5 to simulate EAX game effects and makes them available on Windows Vista/7 PCs. GX2.5 will automatically emulate the latest EAX technologies without additional software.

  • newegg High Signal-to-Noise Ratio (SNR) A high SNR rating means less unwanted noise. Therefore the audio is cleaner which translates to better sound quality. The Xonar DX achieves a 116 dB SNR rating for clear audio in games, movies, and music.
  • newegg Dolby Technologies A rich Dolby feature set is supported in order to enhance PC audio with surround sound. A surround sound experience can be achieved with as little as two speakers or even headphones.
  • newegg GX2.5 GX2.5 automatically emulates the latest EAX technology – up to EAX5.0, to offer advanced environmental audio effects. While enhancing the feeling of actually being in the game, GX2.5 also improves on directional audio information.
  • newegg Low Profile The Xonar DX is bundled with a low profile bracket for compatibility with HTPC cases.
  • newegg VocalFX VocalFX is an innovative voice processing technology to let your voice get into the realistic game landscape (VoiceEX) or to emulate the background scenes in online chat (ChatEX). It also allows you to change your voice pitch to disguise who you are (Magic Voice).

5 out of 5 eggsSounds Great

Pros: High quality hardware at a fair price.
Low profile bracket works great, box had everything I needed for install.
Sound quality out of digital and analog is fantastic. Tested head phones, 2.1 desktop system and home theater.

Cons: Throw away the driver disc and never look back.

Other Thoughts: Use the after market drivers for this card and you can unleash the full potential of this card. Do a search for your card and you will see.

1 out of 5 eggsA Product That Never Worked

Pros: Looks nice.

Cons: The audio card in question could never be recognized under Windows 7. Tried to install in on a brand-new Z97 mobo from Asus (an expensive Pro version).

Other Thoughts: I connected an auxiliary power connector, tried to change the PCI-E slots, but nothing ever worked. The card drivers (tried two different versions) kept telling me to install the card.
Some people say it's an EEPROM mess-up.
I am tremendously disappointed with this product.
Thanks for nothing, Asus!

5 out of 5 eggsWorth the splurge

Pros: I bought this for a build while I was in the process of setting
my credit on fire, I still don't regret this purchase.

The price tier that this sound card is on is perfect for people who
want a nice step above motherboard audio and don't mind spending
$50 > $100. The Asus cards for $50 < are still very solid but here your paying for more shielding, a nicer DAC, more potential to fiddle with settings in windows and sound doesn't degrade with volume. Bass response is great too.

A big bonus to this particular card is, it installs perfectly in Linux. This is a good thing because another Asus card or two have deal breaking bugs in the Alsa driver such as no front panel audio : /

This card has a great front panel audio sound through some decent headphones. Watch the size of your cans though, Ill cover this below.

In addition to music and games, movies sound great too. This card would be a great choice for a HTPC if you have a solid amp to feed(to maintain a good sound path) or of its not so great, you can avoid fuzz. There is no optical!!!!!

Cons: There aren't many cons with this audio card except for a few sort ofs:

Keep in mind, this card does not have digital optical!!! Don't buy it without reading and trash/complain about this card here because you weren't paying attention!

This card will have trouble driving very powerful headphones, the
amp definitely could use a bit more oomph. Make sure you have a nice headphone amp if you have really big cans. Generally though, folks spending that kind of money on headphones would be getting a proper amp as well. Low and Mid powered cans work just fine.

Some of the sound shaping,virtual dolby for headphones tweaks etc don't really sound that great but those kind of tweaks never really do. Just stick with traditional levels and leave the other stuff alone.

I see that people are having some trouble with installation in Windows 10 which, yeah, that is definitely annoying if you just bought the card and your running 10.
With that said,its just due to driver support and the fix will assuredly come. You could be stuck with a card in Linux where its toss up wether the bug will get fixed.

Other Thoughts: Great card. Could use a slightly better headphone amp but that's
my only gripe. Spending another $50-$75 would net you that
but spending more if your not editing or producing would be kind of silly.

1 out of 5 eggsTotal garbage

Pros: Pros: None.

Cons: CONS: Complete waste of money. Couldn't get it installed for the life of me. No connection cable for the motherboard, No connection for the power supply. Tech support kept telling me I just had to plug it in and go. Never happened. Still upset about this pile of junk.

Other Thoughts: If you buy this, good luck.

5 out of 5 eggsAsus DX

Pros: Great sound card. Needs 4 pin which I knew about.
Opted for this over recycling or finding another Xtreme Gamer.
have it running 5.1 Jazz / Room... LFE set to 60 using Cambridge Soundworks "soundworks" speakers - 2 sets. This is a test set up and have upgraded CSW speakers to add later. Why did they quit building speakers - oh yeah.. Creative.
Anyway, it's running almost flat with a slight kick up between 4-8K. Maybe not the best sw suite, but, hey I am not complaining. Get it. LIstening to Will Ackerman.acoustic .wooo...

Cons: they ain't none... wasn't free?

Other Thoughts: Build defined on Silverstone BL03 HTPC case review.
I always add a sound card in this price range. It's really worth it folks.

5 out of 5 eggsExcellent Sound Card Quality

Pros: I recently purchased this sound card. I buy everything ASUS if i can, as i really like their quality on their products. The sound improvement was awesome from onboard sound. I own an ASUS Z97-A motherboard. The sound from the motherboard was good. This sound card just simply is clearer, cleaner, louder in everyway. I am highly impressed. Easily put it into a x16 slot( my pci X1 slots were used or covered) and it works great. Worth the $100.00 (cad). No problem with downloading drivers. however i am upgrading to windows 10 to day so hopefully the card has WIN 10 UPDATE SOON!

Cons: The only con i see is that there is no real Sound tinkering. You can change sound from gaming to music, ECT. I personally like trebble lower, and there are no options that i see for adjusting sound properly. Its generic. You get what you get.

Other Thoughts: I work in an audio car shop. I understand proper sound. I am very finiky with tinkering to get that sound i like. im very picky . I While its not enthusiast grade, i knew that buying it. It does sound great though, i just didnt have $300 for the enthusiast asus sound card.

1 out of 5 eggsA mistake to purchase

Pros: Fantastic word of mouth? Heard its praises at many a review site.

Cons: It gave me no end of problems from beginning to end. It attaches with both a flimsy and problematic to connect molex to floppy peripheral connector and the one included gripped poorly and basically had me getting regular power notices when I tried to install. Replaced it with one from my power supply, and then also had to deal with it not sitting right in either PCI x1 or x16 slots, if bolted in. It needed to be left unscrewed to fit properly in the slot.

Once on, it was dropping 80 percent of the right channel. Something seemingly that hits a fair bit of their customers with no solve. I tried updating drivers, investigating firmware, scanning through forums, updating to the unified drivers (latest and stable)...which didn't solve the problem through many many reboots for driver installs(Really? My video card didn't even need a reboot, and I generally had to do 2 per driver update).

Overall an unpleasant experience and since its a pain to get those molex connectors disconnected, I'm just cutting my losses and leaving it in the case. A complete loss of over a day dickering with it.

Other Thoughts: I really couldn't even tell the difference between the quality coming out of the left and my onboard stuff. They both were able to handle 5.1 24-bit 48k and the on board didn't have me jumping though a single hoop to just plug in and have my entire logitech speaker system working again.

I may have gotten a defective one, but their Asus Xonar DX forum had quite a number of threads of others having the same problem, without any resolution or much notice by the ASUS staff.

Manufacturer Response:

Dear Philip,

I want to thank you for posting this review and I understand that you have an issue with the sound card.

5 out of 5 eggsOnce I got it working, it's fantastic!

Pros: Excellent signal to noise ratio. Dolby Digital Live. Really adds punch to your sound. I previously was listening to music and movie soundtracks through onboard audio and most recently through my Radeon HD6950 HDMI port. I felt like the sound system it was hooked to was sounding a bit anemic and read that the audio carried through a video card's HDMI was really not very good. So I bought this one seeing that it had pretty much everything I was looking for as a HTPC enthusiast.

Cons: No true Windows 8.1 sound drivers that are not beta. No decent documentation walking you through your options and how to get sound through the SPDIF Optical port besides putting in the dongle.

Other Thoughts: This is actually not a very new sound card. The technology for sound cards really hasn't progressed a whole lot in the last few years, so there really hasn't been a need for newer models. I bought this card because I was looking for a sound card as my Auzen X-Mystique was PCI and my video card covered that slot up.

If any of you are having trouble getting sound out of the Optical out, try this: First, go to the Asus website and get the most current drivers for your OS. Go to your Windows Sound Mixer and take it off the SPDIF Optical and put it on Speakers. Then go into the Asus Xonar application and select a multiple speaker setup and select SPDIF Optical. Now test your sound. I had to turn the volume WAY down. The movie I was testing it on wasn't letting me hear a voice track. When I changed it in the Asus Xonar application to Dolby Digital Live, I could hear everything as intended.

Mind you, I found the critical piece of information (change Windows Sound Mixer from SPDIF to Speakers on a google search that led me to a particular FAQ page on the ASUS website. I'm not sure I would have otherwise thought to do that.

I would have deducted an Egg for this not being a smooth operation, but the sound quality really blew me away.

5 out of 5 eggsSounds good

Pros: I've had this sound card for over five years and it's still working great.

Still sounds great.

Cons: Get the drivers from the website, the shipped drivers are usually outdated.

Other Thoughts: This is the third sound card i've purchased (for my own use) and see no need to get anything else.

The sound card, before this was an ancient card with a, VIA Envy24HT-S. It sounded great as well, much better then any on board sound. Driver support was out the window, also the old front port jacks were no longer a standard.

4 out of 5 eggsGood Product bad instructions

Pros: Do not use CD drivers. Download Asus 2012 drivers and then no problems. Found out hard way. For front audio do not use HD audio plug, use only Analog 97 audio plug to work ,attaching to top front of card. Must use extra power cord for card to work. Instructions are p-ss poor

Cons: Bad CD and instructions. Could be much much better....

Other Thoughts: Asus should up date CD shipped with card and improve instruction then they would have much less complains..
