There is no doubt that the Asus Essence STX II 7.1 could be classed as a bit of bargain. In the world of audiophile components the Essence STX II asking price of £218 is less than the cost of a high grade interconnect cable.
Asus have not skimped on the design of the STX II. They are using high grade components throughout and the adoption of the Burr Brown PCM1792A digital to Analog converter will prove very popular with the enthusiast audience.
Asus have incorporated swappable OP AMP's on both the main Essence STX II PCB , and the supplementary daughter card. Additionally, they include a pair of LME49720 OP AMPs and a single MUSES8820 for those who wish to tweak the sound characteristics to suit.
The headphone amplifier is very capable and was able to power most of the high end headphones at our disposal, including the 300 ohm Sennheiser HD800 which we used primarily for this review. The Grado PS1000 also sounded great with the amplifier and with the gain setting set to ‘Extra High' in the software, even the 600 ohm Beyerdynamic T1 sounded focused with plenty of bass clout.
Not many people will be pairing the Essence STX II up with a £15,000 tube amplifier setup, however we thought this configuration would expose any weaknesses. We were pleasantly surprised to find out that the Essence STX II has a very capable dynamic range, and can cope with a range of 24 bit audio tracks at a similar level to source equipment costing many thousands of pounds. There is a certain loss of ‘scale' compared to our Cary 303T Professional SACD player or Naim HDX player (with specialised power section), however we can't imagine many people will complain.
We found that it took a seriously high end system to expose any weaknesses with the STX II, and we doubt that many people spending just over £200 on a dedicated sound card will be disappointed.
If I was buying a sound card for my own rig, I would definitely have an Essence STX II powering my headphones.

- 24 bit/192khz support.
- software is a step up for ASUS.
- OP AMPS can be swapped out.

Kitguru says: An excellent partner for a high end pair of headphones. Bargain pricing.
Really nice review you obviously put a lot of time into it.., it would be nice to see the difference when you connect this card to headsets and speaker systems in the enthusiast pricing range. I’m an audiophile too but unfortunately those nice valve mono blocks and headsets are a dream.
i found this card for 120 pounds on amazon, is it worth buying if i’m connecting it to a Corsair Vengeance 2100 Wireless Dolby 7.1 Gaming Headset and my Bose ® Companion ® 3 Multimedia Speaker System 2.1?
Many Thanks
Hi Anthony – without testing all the products you mention together it is difficult for me to give an answer. I did notice a marginal improvement when using my Corsair speakers over the integrated onboard sound on the ASUS Z87 motherboard. The headphone amplifier is really excellent, especially the gain options which can help drive ‘difficult’ headphones.
The good thing is, if you bought from Amazon and ended up not feeling it improved the experience, you can always return it under Amazon’s policy, without hassle. I would be curious to hear what you thought, if you bought it.
THE SAME SHIT SOFTWARE hahah they need to change it so bad
Great review
