FAQ
Can the Aurora Pro-9 drive high-impedance headphones like the 300Ω Sennheiser HD 800 S?
Absolutely. The Pro-9's high-voltage capability is specifically designed to provide ample power and optimal damping factor for high-impedance headphones, delivering full dynamics and tight bass response.
What is the practical benefit of a "fully balanced" amplifier circuit?
A fully balanced design provides superior noise rejection, especially over long cable runs, and typically delivers higher output power with lower distortion. This results in a blacker background, improved stereo separation, and greater dynamic headroom.
Does the 'Engage' mode color the sound significantly?
No. The 'Engage' mode introduces a very subtle even-order harmonic enhancement, akin to the warmth of a high-end tube amplifier in its cleanest range. It is designed to add a touch of musicality for pleasure listening without obscuring critical details, perfect for enjoying the best music for headphones after a long work session.
Is the internal DAC sufficient, or should I use an external one?
The integrated ESS 9038PRO DAC is among the best available, offering exceptional performance. For most users, it will be an end-game solution. However, the Pro-9's analog inputs allow you to bypass its DAC if you prefer the character of a different external unit.
Do you offer OEM/ODM services for bulk orders?
Yes, we welcome inquiries for custom branding, slight specification modifications, or large-volume orders for resellers and corporate clients. Please contact our B2B sales team directly to discuss your specific requirements.
