The ASUS Xonar Essence One external digital-analog converter (DAC) and headphone amplifier earned considerable critical acclaim, winning a 2012 CES Innovations Award in the audio component category with the industry’s only 8x symmetrical upsampling. The newly-launched ASUS Xonar Essence One Plus Edition further adds a bundled Op-Amp swap kit with six extensively-tested Op-Amps to make sound characteristic tuning easier out of the box, with no soldering required. It also saves customers the need to purchase Op-Amps separately.
More accessible audio modification with six bundled Op-Amps
Op-Amps serve a critical role in audio hardware, amplifying analog signals and determining tone and timbre characteristics. Dedicated audiophiles often choose to change Op-Amps to fine-tune performance, something the original Xonar Essence One supported with its eleven swappable Op-Amps. This feature proved highly popular, leading the Xonar team to extensively test over a hundred different Op-Amps with the original Xonar Essence One in order to check for a wide audio tuning range. The six Op-Amps deemed most unique in their impact on sound character were selected to be part of the Xonar Essence One Plus Edition, the first USB DAC with a bundled Op-Amp swap kit. By combining the original Texas Instruments TI-NE5532 Op-Amps with four Texas Instruments TI-OPA2132PA and two NS-LM4562NA Op-Amps, the special edition allows for five unique tonal impression customization options. The kit even includes an IC clamp, a screw driver, and an Op-Amp swap guide which shares various Op-Amp tips based on the Xonar team’s findings. These make swapping any of the existing eleven Op-Amps easy for quick audio modification based on personal preference. The kit further offers compatibility with other Xonar products, including the Xonar Essence ST/STX, Xonar Xense, and Xonar DS/DSX.
