Experience: 4 Weeks


Great Sound
Lots of customisation options
Hard to travel through interface
This does make a huge difference in sound from the normal Realtek sound card embedded.

Experience: 2 Months


Great sound!
Good Customization Options!
Clunky Interface
I had been told by my gaming friends that there wasn't much difference between onboard Realtek sound and a dedicated sound card. My last computer had X-fi built into the motherboard, and I was quasi pleased with it. Well, after getting this soundcard with my new rig, I was blown away with the quality of the sound. I do have a Sennheiser headset, so I was expecting it to sound decent, but it was 10x better than my old setup. Music is so rich sounding, and ingame sounds are incredible as well. The first game I fired up was GTA5, and with all the gun shooting, car driving, helicopter flying, music beats, this soundcard made it awesome!
The only down side for this card is that the interface is a little awkward, but I think it is just a matter of getting used to the buttons.
There is also 3rd party drivers, but I haven't been brave enough to try that yet.
It also took the Windows 8.1 -> 10 upgrade seamlessly.
10/10 would buy again!

Experience: 5 Days


Does what I need it to. (e.g. I have external amps and an external dac I send its signal to, so I just need it as a sound processor)
Looks good.
Good measurements, features.
You won't hear any from me at this point.
In summary, I recommend this soundcard if you already have better DACs and amps and just want to use it as a sound processor from your PC.

Experience: 3 Weeks


- Clear mids and highs, with good, deep bass
- Dolby 7.1 sounds amazing
- unbelievably affordable price, especially when price matched
- no headphone amp, although it's not needed unless you have like 200 ohm impedance headphones
Remember to use unified drivers! Mine works with no problems and it was so easy to set up EQs with Xonarswitch

Experience: 1 Months


- easy to install
- good sound overall
- power cable
- bad software
Bought this to replace my Creative based Auzentech X-Fi Forte. Connections and installation was easy, plugged the front panels HD audio without hassle.

Sound quality, it depend which use you intend to do. I find the audio different on some outputs. The sound I use on the speaker was too muffled on my speakers while it was too hissy on my headphones. I rarely had to use the software EQ to adjust the sound on my previous sound devices, and sadly the software is not very friendly, doesn't look very pro and the EQ doesn't do very good job. The tests are too awkward quality I can't barely hear what the test woman voice says, leave me wondering if my sound settup is good or bad.

Experience: 2 Years


Great sound
Not the best driver, secondary power connector is broken out of the box, terrible support - 3 year warranty is a lie
Agree with other poster - secondary power connector is broken by design. And if you think you have 3-year warranty - good luck!

Experience: 4 Months


easy to install.
huge improvement over the sound card on the motherboard
nothing remarkable, just a good sound card.
old motherboard does support 5.1, but when i upgraded to z906, nothing really changed, i got a bigger bang than the old z10, that's all. but clearly the motherboard is taking a toll, because it just kept restarting the speakers. so i got the dx7.1.
there hasn't been a big improvement over the sound quality, i'd say 20% tops, but the base is better.
a good card to get over the stock ones.

Carbon Rod
Experience: 1 Weeks


Excellent sound. A great improvement over on-board sound.
Nothing really.
I purchased this as an alternative to my motherboard's on-board sound solution after it started developing some weird issue. Rather than try to fix that issue, I decided to dodge the whole thing by installing one of these and I do not regret it one bit. The control panel also allows for numerous more custom settings than my on-board sound did. All in all, a great, moderately low cost upgrade over on-board sound.

Experience: 2 Days


Amazing sound
Excellent features
Low profile (bracket included)
setup a bit tricky
Need to update  drivers for Windows 7, but works great
This is the card you need if you want to set up an HTPC, if your Mobo is not equiped (older) to handle Dolby Digital, or home theater sound, or even if you want to upgrade your onboard sound. I tried three different cards from Asus, before I found this one. There is a difference between the price points of this and the cheaper cards. The DX, will decode Dolby Digital in Full 5.1 and 7.1 right out of the box, where as the cheaper models just seem to have a pass through for this feature, which I believe needs some kind of software decoder to make anything work...not this one though, but be aware if your using anything newer than Vista you will have to do some updates from Asus's website for the audio driver, and you will have to change some of the audio settings in the control panel as well for Windows 7. But once up and running... it works great, the sound quality is this card! This review was modfied by poster f 03-02-13 10:34 AM

Very good sound quality, and good driver utility
Constant problems with power
So this card gives me sort of mixed feelings. On the one hand the sound quality is amazing. There's no arguing that. The only problem is that the power connection on it seems to be quite finnicky. For example, sometimes when I move something around in my case the power cable gets touched just a little bit, and when I restart my computer I get a message saying that the power is unplugged, when it clearly isnt. You have to have the power connector plugged in perfectly, and yes, I mean perfectly. That being said, once it is plugged in correctly the card is great. Its just annoying if you tinker with your components a lot, because you'll find yourself constantly having to power down your computer and play with the power connection a bit.

Ive also looked this problem up online and I'm not the only one getting it.

Comment: A canadian reveiw of the ASUS Xonar DX 7.1
Posted by: {[The-Ghost ]} @04/28/08
Comment: TechReport's review of the Asus Xonar DX. A very high-quality sound card at half the price of the Xonar. the DACs aren't as good, but still very high quality. Editor's choice.
Posted by: willyo @04/12/08
Comment: Ths card gives excellent performance at a fair price for the features. It's main drawback is the lack of DTS and limited connectors in that The only ways the Xonar DX came up lacking are in its limited number of I/O jacks meaning that you are sharing the digital-out with the line/mic which is inco

Comment: Tech report editors choice. "The Xonar DX is more than just a fantastic sound card. It also cements Asus as the most credible—and importantly innovative—alternative to Creative's dominance of the PC audio market. Enthusiasts have been waiting for such an alternative for a long time. "
