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).

Still love my Asus DX

Cons: None

Using for around 9 years, same card in 4 builds

Pros: This card has lasted me for a long time, I have used in standard stereo, and now optical to a repurposed pioneer 5.1 receiver. Every time I upgrade a pc with new board and cpu, this card transfer's over.

Cons: For a old card, it is overpriced.

Other Thoughts: I see a lot of people have trouble with this card, I presume something has changed with manufacturing or material's since I bought mine. Now that I think about it, I may have bought mine used.

Major issues with this card

Pros: Software is nice

Cons: The ASUS Xonar products have a major bug that has never been fixed. Randomly a very loud screeching noise pops up that is at 100% volume and blows your ears off and scares the heck out of you. This happens very often with the newest Windows 10 versions. Does not happen using spdif or Linux. There are many reports on the internet about this but no solutions. Everyone that has this product has experienced this issue at some point.

Other Thoughts: Do yourself a favor and buy something else.

Junk Straight Out Of The Box - You Have Been Warned

Pros: Board has a clean design. Software "seemed" to work.

Cons: Straight out of the box this was defective on the line-in. Both channels were clipped on the positive side, but looked normal on the negative side. Without something like Audacity or Goldwave, this wouldn't be noticeable. But in the software, ripping vinyl, the clipping was very evident. The other problem was the volume was low. It isn't even worth getting another one in because something this severe should never have left the factory.

Unlike the other reviews complaining on the power connector, mine seemed okay in that respect. Actually, I was surprised at how sturdy the connector was. Just too bad the sound from the card is crippled.

Excellent sound card! - Windows 10 drivers work perfectly on my Core i7-8700K computer

Pros: - Easy to install with included power connector from card to molex power supply connector (installed in PCIe 1x slot)
- Includes HD Audio connector on card to reconnect front panel headphone jacks after disconnection from onboard audio
- Xonar DX Audio Center software is where the magic happens with this audio card
- Superior sound over onboard 7.1, and well worth it, in my opinion, especially for games

Cons: - Just one: No mention of software in Quick Start Guide or any other documentation. Software installed when Windows 10 drivers where installed, but no shortcut was on my desktop to indicate software was include with the driver. There was not mention of software anywhere on their site or in their documentation. This means the end user MUST know that it is included.

Other Thoughts: Because I didn't realize at first that there was software installed along with the Windows 10 Pro 64-bit driver I downloaded from ASUS' website (no indication there was any), I thought the front panel headphone connectors just didn't work. It wasn't until I realized there must be software and looked under my START menu in the ASUS folder that I found the Xonar DX Audio Center app. I started it up (after pinning it to my taskbar for quick access) and clicked the triangle at the bottom right to open it up further, I discovered that under Analog Out pulldown there was an FP Headphone option. I selected that and it was like turning on a light - my headphones worked while connected to my computer's front sound jacks! I wear headphones all the time since I live in an apartment and the 7.1 sound is just more immersive for me with them on in games. Each user will need to tweak the sound settings in this software to their taste. For me, since my game (War Thunder) uses classical music during play, after pushing the EFFECT button, I chose CLASSIC, and under ENVIRONMENT SIZE I ticked S for small. Then under Environment (above Environment Size) I picked PADDED CELL to kill much of the echo or wide open sounds. That combo works for me. Each user will need to setup what they like for themselves.

Here's my computer system, should this be of interest or help others decide whether to give this great sound card a try:

Core i7-8700K
ASRock Z370 Extreme4 motherboard
Corsair Vengeance LPX 2x8GB CL15 DDR4 3000 RAM
Samsung 960 Pro M.2 512GB NVMe PCI-Express SSD
MSI GeForce GTX 1080 Ti Gaming X video card

Final thoughts: The Windows 10 drivers from ASUS work just fine, at least on my computer system. I've read several negative comments about how they don't work or have issues. Not for me. Also, my review relates more to my experience with 7.1 surround sound headphones. I don't have a 7.1 speaker system connected to my computer - just 2.1 that I almost never use. As I stated, living in an apartment means I need to use headphone most of the time, and I prefer that anyway since my game play is more immersive that way. I'm extremely happy with this purchase. The ASUS Xonar DX 7.1 sound quality is many times better than the 7.1 onboard sound I had been using from my motherboard.

Worst thing I've bought on new egg

Pros: Great sound (see cons)

Cons: If you start up a game, or anything that uses the GPU, there's no shielding on this card (something I never even thought would be an issue), and you end up with a horrible buzzing sound

NEWEGG and Rebates

Pros: NONE - 0 eggs, It has a defective design for sure.

Cons: Known defect, many reviews tell of it - wish I'd read them. Mine failed before 30 days this time. Asus has problems - they have grown too fast, offer bad support now on their products that are not Motherboards. It burned out 2 expensive speakers when it went out suddenly and loudly - smoke even.

Other Thoughts: Newegg seems to be out of stock on this. Why? Perhaps they were selling that DEFECTIVE stock using a "rebate" as the bait. The switch - they won't accept returns with UPC codes cut off the box, which you have to do to get the rebate. Get it? A purchase that, by design, can never be returned. You paid for their defects, hey think of it as a bailout....

ASUS Xonar DX 7.1 Channels 24-bit 192KHz PCI Express x1 Interface Sound Card.......Terrible product....no eggs

Pros: None

Cons: Everything

Other Thoughts: I have always trusted Asus products since way back in the BX board days, Asus always meant quality, so it pains me to give up on this product. I have never wasted my time to write a bad review on anything and I have never been more than patient. Now almost 3 years later I am done trying, and believe me, I have tried everything, wasting countless hours trying to get this to work properly, using different drivers and trying it in different computers and the results are always the same. Asus should be ashamed to have ever released this $100 piece of garbage. It may be too late for an RMA which is nobody's fault but mine, but I will think long and hard before buying any Asus product again.
