I can honestly say it will be the last sound card I will ever buy.

The output is so clean, so clear and so precise that you can differentiate the music produced from different musical instruments.

Can report that the Asus Xonar ST increased sound reproduction in a very significant way.

I've had this card for over a year and I'm very happy with the quality of audio reproduction. I use it primarily for headphone playback (Sennheiser 595, 120 Ohm version) of my compressed lossless audio music collection (FLAC, created with EAC) on a Windows 7 x64 desktop.

In order to get the best performance out of the card I suggest the following settings for headphone playback:

--Install the latest driver from the Asus website (currently 7.12.8.1794). In the Asus control panel select: "2 Channel", "PCM 192 kHz" and "Headphone". Also, click the "HF" button in the DSP section which puts the card in Hi-Fi mode and disables all sound effects.

--From the Windows control panel open the 'Sound' panel. In the 'Playback' tab you should have 'Speakers (ASUS Xonar Essence ST Audio Device)' as the default device. Right-click 'Speakers' and select 'Properties'. In the 'Speakers Properties' panel that opens select the 'Advanced' tab. Select '24 bit, 192000 Hz (Studio Quality)' from the drop-down menu in 'Default Format', and make sure both boxes are checked in the 'Exclusive mode' section and click 'Apply'.

--Install the free and excellent foobar2000 player with the WASAPI output support component which allows exclusive control of the audio driver, bypassing the mixing/resampling layers of DirectSound (DS). To do so, after you install foobar, go to the 'Components' section of the foobar preferences and click 'Get more components'. In the webpage that opens find 'WASAPI output support', download and double-click the module installer and then click 'Apply' in the foobar 'Components' window. It will restart foobar and if everything goes well you should see 'foo_out_wasapi' in the list of modules. Now go to the 'Playback' section of the foobar preferences.

I am writing this review to let you know that this Asus Xonar Essence ST audio card sounds better than another version STX which is designed for PCIE. I purchased two versions and auditioned them carefully. Both sound far superior to Creative Elite Pro, Fatal1ty professional and HT Omega Claro Plus that I have listened before. But vocals of STX sound nasal and rugh compared to ST. ST sounds more natural and refined with much deeper and more realistic bass sound reproduction. The Stereophile magazine reviewer said ST and STX appear to be identical, but they "indeed" sound different. They are not merely designed for different interfaces. No wonder ST is priced higher. I decided to keep ST and return STX for refund.

My speaker system is Creative GigaWorks T3. It sounds excellent with ST and STX. Today I will receive Razer Mako. Can't wait to see how it will play with ST.

I have this card running LME49720HA and LME49710HA op amps connected to M-audio speakers with thick gold plated RCA cables. With the stock opamps this card is good. With the LME's this card sounds simply amazing.

My power supply is an Antec with very low electrical noise and a large RF choke filter on the card's power cable also. My UPS/power strip is also noise filtered.

I can hear an ocean of sound, from the deep dark depths to the rippling, curling, crashing tips of the waves of audio coming forth. No static hiss at all unless it was in the track itself. So clear that when you watch a movie you swear you can hear the director breathing behind the camera.

The stock JRC opamps are bassier, good for music. They lack the razor sharp sound of the LME's though in the high-end and mid-range.

I Bought this to replace a 6 year old Sound Blaster Audigy SE that I've used across two computers now. I figured that I would treat myself to a nice sound card as well as some nice headphones (Sony MDR-V6).

To anyone with installation issues, these were my steps:

Uninstall Creative Software and Drivers
Uninstall SB Audigy from Device Manager
Restart
Boot into BIOS and disable the onboard audio (I have an AMD 785G based motherboard)
Shut Down
Installed card WITH molex attached (I feel like some people may have forgotten that step, so the card won't work without it)
Booted up and installed the latest driver package (I believe only the latest version supports Windows 7 64-bit, which is what I run).
Restarted
Works

Note: It doesn't default to headphones, so you have to tell it to play from headphones in the Asus software. Also, my computer didn't default to the sound card automatically, it had defaulted to the sound chip on my AMD/ATI Radeon 5670. After changing the default sound device via the sound control panel in control panel, everything worked great. I set the correct impedance and to HiFi and it just sounds great. I even set it to do PCM at 192KHz through the Asus Software.

I couldn't tell you if it's just the headphone amp, or just my new headphones, or actually the sound card, but everything sounds great. I am hearing sounds I hadn't before! Whether or not it's truly the sound card, I'll have to see. I'm considering using my PC over my PS3 for DVDs and Bluray so I'm just curious as to which will make my Creative Gigaworks sound better.
