FEATURES

The Essence of Sound Following considerable positive feedback from customers on the excellent sound quality of Xonar Essence ST/STX sound cards, we developed the Xonar Essence STU USB external digital-to-analog converter and headphone amplifier. Based on the acclaimed design of Xonar Essence ST/STX and going beyond their already high standards, it offers even more premium audio quality plus easy controls and connectivity for discerning music lovers who needs a good DAC and headphone amplifier to drive the full capabilities of their high-end headphones. High quality precision audio Xonar Essence STU delivers clean, clear, and low distortion sound with 120dB signal-to-noise ratio (SNR) thanks to exacting hardware design and top-notch component selection. Digital-to-analog converter (DAC) High fidelity Texas Instruments PCM1792A DAC delivers accurate digital-to-analog conversion, sensational audio clarity, and low distortion. Precision clock tuning technology Xonar Essence STU embeds a precise clock tuning IC that kills jitter prior to signal processing, ensuring the highest fidelity with extensive detail and lively sound imaging. Audiophile-approved capacitors WIMA FKP2 and Nichicon Finegold capacitors deliver balanced and rich sound. Asynchronous audio transfer Asynchronous USB transfer mode separates unstable and noisy clocks generated by the computer or its USB interface logic, maintaining sync with master clock circuitry on Xonar Essence STU. Balanced (or mirrored) PCB layout Symmetrical analog output path ensures balanced and truthful representation of all sound sources and minimal crosstalk. Headphone amplifier Renowned TPA6120A2 headphone amplifier supports up to 600ohm impedance, driving all headphones available in the market. It empowers your favorite set with dynamic and detailed sound. Headphone gain switch Xonar Essence STU offers readily accessible switching between low and high gain settings, accommodating better listening experiences across a wide range of headphones, from in-ear headsets (typically 16ohm-32ohm) to premium full-size headphones ( up to 600ohm). This is especially useful with the increasing popularity of mobile devices, which normally ship with low impedance/high sensitivity headsets. Convenient tonal tuning Xonar Essence STU has room for three swappable Op-Amps (operational amplifiers), which you can replace to adjust tonal performance based on personal taste. This open-ended and customizable design is inherited from previous Xonar Essence audio products, and remains true to the series’ commitment to accommodating as many audiophile preferences as possible. By-passing volume jumper switch The included jumper switch re-routes sound and allows Xonar Essence STU to be used as a pre-amplifier in conjunction with a dedicated power amplifier. You can opt to adjust master volume directly on the power amplifier without having to reach Xonar Essence STU controls. Select-able DC servo headphone output Many music enthusiasts choose to solder a DC servo on their DAC to minimize power-up pop noise on the renowned TPA6120A2 headphone amplifier. The dedicated DC servo on Xonar Essence STU offers a convenient and solder-free alternative.

    Return of merchandise (RMA) and Warranty

    We want you to be happy with the purchase you have made from us. If you are not completely satisfied, you may return the product to us and we will either refund, credit, repair/replace it, subject to the below terms and conditions. 

    You can return purchases for a refund (excl shipping). Please notify us within 7 days and ensure item is ready maximum 10 days after delivery date.

    Please ensure to log your return request within 7 days of receipt of your item. Please ensure to select the correct reason for return:

    - Changed my mind / Item exchange

    - Faulty on arrival

    - Incorrect item received

    All items are covered by a 12 month warranty (unless otherwise stated) which will be honoured directly by GeeWiz. All products will either be replaced/repaired/refunded depending on stock availability. Products will require evaluation by GeeWiz before a warranty claim can be accepted.

    Should the item being returned for assessment be found to be in good working order, unfortunately, there will be a collection fee that will apply.

    The collection fees are as follows:

    - For returns on items that were sent with free shipping: R198

    - For returns that had a surcharge, the same surcharge will apply for collection.

    Please log your return on your account, under the returns manager.

    We do not reimburse your fee to ship to us, but we will pay for return shipping if the item is subject to replacement. If the item you wish to return was ordered incorrectly / is no longer required / you have changed your mind, there is a collection fee that will be charged (please refer to the above) and this will be deducted from the refund amount once the supplier has credited us. Please note GeeWiz will only cover return shipping of a faulty unit within 6 months of purchase, after which, a shipping fee (starting from R198) will be applicable to you for the return of the unit.

    Any disputes relating to ordered items being short/incorrectly shipped will only be entertained if reported to GeeWiz within 3 days of delivery/collection.

    Refunds are subject to inspection of item(s) - in some cases, items will need to be sent to supplier for evaluation and testing. This can take up to 15 working days. Once a refund has been approved, this may take 3 - 5 business days to be processed.

    ALL returns are subject to a 15% restocking fee if item is no longer in BRAND NEW condition or if item seal/packaging has been broken.

    Please re-package safely and include all original product packaging.  

    All software products are unfortunately not eligible for credit or refund once purchased.

    After the 6-month period, you will no longer be eligible and won't be able to receive a refund. We can however replace or repair depending on the outcome after our team of professionals has inspected the product.

    Should a warranty sticker not be present on an item, the warranty is immediately null and void.

    Batteries are covered under warranty, but please note that GEL, AGM and LEAD ACID have limited cycle runs. These are typically around 200 cycles and may run out before the end of the warranty. Once the cycles have been depleted, it means the battery has reached the end of life and will no longer be a warranty claim.

    GeeWiz reserves the right to refuse a refund if the item is damaged from misuse, items are missing, or if the product is altered in any way. 

    GeeWiz or its affiliates are not responsible for damage or loss of any kind that may occur as a result of using or misusing any product purchased from us.

    The warranty will no longer be valid, and GeeWiz will not be responsible for damage or injury of any kind resulting from:

    • Electricity fluctuations and surges, lightning strikes, faults in the building wiring, faulty installations, and improper use of controls
    • Failure to use the product in accordance with the operating instructions and or general misuse and or abuse
    • Damage caused by a superior force (vis major) or if the product has been infested with insects or pests
