Original Audio OPA-Q2.1SE is a headphone amplifier and DAC. It delivers excellent performance thanks to its carefully designed design. Its varied functions and numerous inputs and outputs make it a very good all-rounder.
All OPA-Q2.1SE designs exhibit great rigor, both in the architecture itself and in the selection of components or assembly. Thus, fully balanced headphone amplification circuits provide very low distortion. The headphone amplifier section is also based on the use of discrete components.
Two high-quality dual 1612A AOPs also perform filtering functions, providing excellent sound clarity. A specially designed analog audio processing module also enhances this neutrality of sound, providing a certain musicality.
The OPA-Q2.1SE shows great versatility with these different inputs and outputs. Indeed, on the box we find a USB type C input, an optical input and a coaxial input in addition to bluetooth.
In addition, at the output level there is a 6.35mm Jack output, a balanced 4.4mm Jack output, as well as a balanced 4-pin XLR headphone output. On the other side, there is a balanced stereo XLR output and a stereo RCA output, allowing you to connect the OPA-Q2.1SE to an amplifier or powered speakers.
The OPA-Q2.1SE digital-to-analog conversion stage features a highly efficient ES9038Q2M DAC chip, delivering excellent performance for accurate and detailed audio reproduction. This DAC is coupled with the XMOS USB interface, allowing you to enjoy high-resolution audio streams up to PCM 32bit 768 kHz and DSD64.
All components are housed in a durable CNC machined aluminum housing. Additionally, this frame has a discreet yet modern aesthetic that will fit into many HiFi systems.
