ASUS Xonar Essence ST/STX soundcards

24 January 2010
  • Conclusion: The Xonar Essence STX and Essence ST soundcards are by far the least expensive way of turning a PC into a genuine high-resolution audio source I have yet encountered. Neither the Essences' resolution nor their low levels of noise are compromised by having to operate in the electrically unfriendly...

ASUS Xonar Essence STX PCI-E Sound Card

Benchmark Reviews
16 November 2009
  • Conclusion: As the performance graphs show, the ASUS Xonar Essence STX is a high achiever. It blitzed all tests, bar one, where the Xonar Xense got a slight upper hand in frequency response.

  • Cons: Need pricey equipment to appreciate the added quality of sound, EAX emulation isn't quite as good as a native hardware solution, No hotkeys to quickly alter settings in Xonar Audio Center

Elite Bastards
18 May 2009
  • Conclusion: When we came to the climax of our review of Auzentech's new X-Fi Forte a couple of weeks ago, we labelled it as our new "king of the hill" as far as discrete audio solutions go.  Indeed, it was almost a minor miracle in the way it squeezed so much functionality into such a small board, and without...

Asus Xonar Essence STX

Overclockers Club
3 April 2009
  • Conclusion: As with most products, I was slightly apprehensive about the Xonar Essence STX before I heard it. I asked myself, how could a small, simple amplifier on a soundcard perform anywhere near as well as a standalone headphone amplifier?
  • Pros: The DAC, capacitors, and op-amps on the card produce an extremely pure and transparent sound, Hugely dynamic and accurate sound on any headphones using the onboard headphone amplifier, Headphone amplification works for the front panel (case) audio sockets, Flawless driver compatibility in Vista 6...
  • Cons: The GX mode isn't a 100% exact emulation of EAX

  • Pros: The best music experience you'll ever have on a set of headphones on a PC, Extremely high quality audiophile build with swappable OPAMPS for those with a need to tweak
  • Cons: Not for gamers or casual listeners, Price may be hard to justify for some
