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).

3 out of 5 eggs build quality is subpar but when you figure out the problem ahmen

Pros: very good sound quality when you discover what the problem is i will explain in cons
i use the aftermarket drivers and they are beautiful even on these hp stock spare speakers lol before i fixed the power cable i could'nt put my speakers past 20% volume without distortion now i cant put it to 100 due to neighbors lol

the whit power connector isnt actually soldered to the pins n the pcb so it tends to come loose to fix this just push the white adapter in requires a little force but then it just slides back and it fixes the "china grade" floppy cable problem

Other Thoughts: so overall i actually love this card but the cheapos should have put a different power adapter on it because when it is loosens not enough power is supplied and the sound gets distorted. Funny thing is the only reason i discovered this was when i was getting ready to pack it up haha the power cord tugged slightly and i noticed the white bracket wasn't at all on there right.

4 out of 5 eggsBoom

Pros: Excellent signal to noise
Excellent sound quality
Solid output selection
Software adjustability

Cons: Power plug can be finicky.
Started losing the right channel after warranty expired. I used to be able to pull the jack and plug it into another port to get the channel back. Now when I do it I either get a BSOD or the audio breaks till reboot. 4 years of use.

Other Thoughts: I use my computer to play games, listen to music (FLAC lossless only), and watch movies. My xonar outputs to a vintage 70s pioneer receiver that has been cleaned up internally. The A channel goes to a pair of floor standing three way speakers. The B channel outputs to an adjustable active line level converter to RCA. The RCA output is fed into a vintage 98 PPI powerclass 2150 amplifier which powers a single JL 12w6v2 in a sealed 1.5 cu ft enclosure. The amplifier is fed power by a 650 watt Antec PSU I recapped and modified for 12 volt output (12.2v output under load).

Why did I tell you this? Because I wanted you to know how serious I take audio. With the integrated audio my system sounds okay. The extension on the low end is pretty bad. With the xonar I get sound below 20hz with cone movement down to almost 5 HZ. On the high end I get sparkling clear sound. When listening to properly recorded symphony music I can close my eyes and it honestly feels like I'm there in the crowd. This card absolutely blows away my old soundblaster 5.1 card.

The sound card has given me no issues with compatibility. I'm not a fan of EAX and such though (sounds artificial even with a soundblaster card) but the features performed like they should.

The built in software is solid giving you a good deal of control over the card's output.

An excellent buy and if you have some extra money you might consider getting the more costly asus card for the upgradable op amps and the improved shielding. If you don't have high end equipment then this xonar will cover you fine.

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.

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.
