Summary
If you are a real audiophile and live in xp era, would highly recommend.

Experience: 7 Days

Pros

- Sound is significantly cleaner and clearer than before
- Card looks great in my desktop
Cons
- Software looks/feels pretty tacky
- Needed to edit a DLL to get the software to install on my Win10 PC
- No way to have audio-out to speakers and headphones simultaneously
- No way to quickly switch between headphone and speaker outputs
Summary
Overall, it's a fantastic card. My only complaints are around the software. You can output sound to headphones and speakers at the same time - this wouldn't be an issue on its own...but the fact that you also can't quickly switch between headphones and speakers (have to open the software, click a little button, then change the selection in a drop  down box) makes it pretty annoying. To get around this, I just created an Autoit script to do this for me.. so that's nice at least.

Nothing much else to say.. if you have only onboard audio and have issues like buzzing, humming, poor fidelity, and also have good enough speakers/headphones to hear subtleties of the sort - then this card is a fantastic buy.

Pros

Works okay for basic stereo
Cons
Asus not providing WHQL drivers - Tiawan engineers says for China only, but god drivers also in Europe.
Summary
As soon as Xonar Essence STX is installed to PCIE 3 system, PCIE 2 Display card's HDMI drivers are hawked to create  a ghost HDMI which is of course always flagged in Device Manager. Numerous other system problems arise around display and sound. AMD and Microsoft Research spent months working on a support ticket: told me 3rd party CMedia is problem: its drivers are "illegal". ASIO4ALL drivers maybe? No idea what Asus is doing in China and Europe, but something related to WHQL, this card is garbage for 60% of Windows 8 users in North America. NCIX built my Windows 8 system, and I bought this card a year later, 2013 OCT 16. NCIX Sales told me it would work fine, and NCIX Tech installed the card for me into my NCIX System, as I requested. Nothing but trouble ever since. Now, a year later, I give up. Paid $250 for this junk sound card. Wish there was a ZERO STAR rating. It makes a 11db sound, so very generous today, 3 stars.

Pros

Great build quality, aesthetics, sound, and more!
Cons
Incredibly pleased with this sound card!
Summary
Both the Hardware and software are great but I really suggest people purchase a high quality headset with this, obviously. I'm using a 600Ohm headphone and it has no problem powering it!

Pros

-great sound as usual
-looks great
Cons
-drivers arent the best
-make the card powered by sata already
Summary
Great sound as usual from asus. a must buy if you are working with music and have a large set of cans that need powering. the op amps are swappable if you are into that. the stock ones are pretty good already

Pros

Sound quality
Cons
None
Summary
I was skeptical at first wondering if there was a clear difference between on board audio and dedicated sound. After using this sound card I was amazed at the difference it made when listening to music and gaming. It has a wide range of effects and modes for anything you would want to listen to. I definitely recommend this product for anyone who can spare the money and enjoys high quality sound.

Pros

Very Clean D/A output. Inaudible noise even at extra high gain setting and master volume at 100%. Upgradable OP-Amp for customize-ability. Excellent high end D/A chip.
Cons
Requires Molex power connection and the connector head is difficult to get a proper connection. Marginal SQ upgrade from my previous Xonar DGX sound card. Headphone amp is also only marginally better than the one on DGX on Extra High Gain +18db. (Beyerdynamic DT 990 Pro 250ohm). Driver support is dated back to June/2011 for Windows 7.
Summary
Overall I'm satisfied with my purchase but I was expecting it to perform better to my expectation. You'd notice a big difference in sound coming from an on board audio w/o dedicated headphone amp but this sound card can just be considered as an entry level audiophile in terms of its headphone amp, however, its DAC chip is proven to be a very high end unit that are sold in ~$1,000 DAC receiver/external unit. You may still consider this a good purchase just for the DAC performance alone and it's got front R/L analog output in case you ever want to pair it with a better external amp.

Pros

-sounds great with my hd800s
-sounds really good
Cons
-not really. just that floppy power is annoying. if you are making a revision, please consider using a sata plug instead
Summary
Pretty good sound card. much better than what the other major companies offer at this price range

Pros

Great sound, easy to install and configure
Cons
does require a little fiddling with the equalizer
Summary
It's all set up for audio reproduction so out of the box it does sound a little flat, with the included software though there are dozens of preset combinations to choose from, after a few minutes you'll have it sounding just how you want it.

looks great, sounds great and my favourite feature is the software switch to go between headphones and speakers, so you can leave both plugged in all the time and just slect the one you want at the time from the dropdown menu.

Comment: The sound quality of the Xonar Essence STX far surpasses any commercially available and viable sound card in it's price category. Barring sound cards costing £200 upwards, the Asus Xonar really is musically the best card you can get at the moment.

Comment: At around $200 US, this card is definitely not for everyone. However, anyone that enjoys music, or who wants to enjoy it all over again should be hitting the stores for this. It’s truly a high performance product.
