When I decided to upgrade my audio setup, the Asus Essence Stx II caught my attention. Here’s my detailed guide based on my personal experience and research to help you decide if this sound card is right for you.
Why I Chose the Asus Essence Stx II
I was looking for a high-quality internal sound card that could deliver exceptional audio clarity for both music and gaming. The Essence Stx II stood out because of its audiophile-grade components and excellent reputation among sound enthusiasts.
Key Features That Impressed Me
- High-Quality DAC: The ESS Sabre 9023 DAC chip provides crystal-clear sound with low distortion. I immediately noticed the difference compared to my onboard audio.
- Dedicated Headphone Amplifier: It supports high-impedance headphones, which is perfect if you have professional or audiophile headphones. My headphones sounded fuller and richer.
- Multiple Audio Outputs: I appreciated the flexibility with optical S/PDIF output, RCA line out, and 3.5mm jacks, making it easy to connect various audio devices.
- Low Noise and Interference: Thanks to its shielded design, the card minimizes electromagnetic interference, ensuring a cleaner audio signal.
Installation and Compatibility
Installing the Asus Essence Stx II was straightforward for me. It fits into a PCIe x1 slot, so make sure your motherboard has one available. Also, check that your case has enough space since it’s a full-sized card. The drivers were easy to install, and Windows recognized the device without issues.

- The Asus Essence Stx II is an older model, so it may not have the latest connectivity options like USB-C.
- It’s designed primarily for Windows OS; macOS or Linux support might be limited.
- Price-wise, it can be a bit of an investment, but for me, the sound quality justified it.
Final Thoughts
