Closer Look: ASUS Xonar Essence STX

The Essence STX uses a slick black PCB to house its components. The bracket is coloured gold to match the gold plated TRS sockets, which adds a touch of class.


A black brushed-metal electromagnetic shield covers the analogue components to ensure quality output.


From left to right are the right/left RCA connectors, TRS (6.35mm) line out/in, and optical S/PDIF out.


Included is a S/PDIF TOSLINK adapter, and a 3.5mm to 6.35mm TRS adapter. There's also a 3.5mm-to-RCA adaptor cable to allow 3.5mm devices to use the RCA connections.


Along the top of the card are the auxiliary input and front panel connections. The auxiliary connection is used for input from other devices such as TV tuner cards.


The molex connection provides power to the Texas Instruments TPA6120A2 headphone amp. Beside it is an alternate S/PDIF out header.


All considered, the Essence STX has a great selection of inputs. It's nice to see 6.35mm TRS jacks being used instead of 3.5mm connections.

Good Review.
I am curious about the THD peak at 1Khz.
Is this something commonly seen?

If the purpose is just for headphone listening, how this would compare to a similarly priced external DAC/Headphone Amp like a Fubar III or Fire-eye?

My self i dont game much but i love my music i do have to admit this card will test your sound system and if you set yourself up right you'll listen to sound with the highest quality..My sound system is average the Logitech 5500 but i set up my system the right way them i go as far as converting to Flac music which is 24 bit/96khz 6 channel with the kbps in the 8640 range so thats extreme HD sound also true surround its what you call.. ear candy...
