AIYIMA A80 High-Fidelity DAC & Headphone Amplifier User Survey

Dear Audiophiles,

AIYIMA plans to develop a pure DAC & headphone amplifier version based on the A80 architecture.

In addition to keeping the A80’s signature VU meter display and full input options, we are considering adding a “high-fidelity Bluetooth TX” function.

Your feedback will directly influence the final product’s features and design choices.

Very appealingNeutralNot useful

Part 3: Hardware & Audio Performance

8. Which output interfaces do you consider essential for the A80 headphone amplifier version?

6.35mm Single-ended output4.4mm Balanced outputXLR Balanced pre-out (for monitor speakers)RCA Pre-out

9. What is your tolerance for the amplifier’s noise floor?

Very high: absolute silence for IEMs, no hiss at all.Normal: acceptable as long as there’s no noticeable noise when driving large headphones.Low concern: not sensitive to noise floor.

10. Which upgrade would most motivate you to buy?

Core DAC chip upgrade (e.g., ES9038Q2M → ES9039Q2M)Significant power increase (supports 2000mW output, easily drives high-impedance headphones)More digital filter and tone adjustment options

Part 4: Interaction & Display Logic

11. Which info would you most like to see on the color screen?

Dynamic VU meter / Spectrum (retro aesthetic)Bluetooth pairing list and statusCurrent audio sample rate / file format (DSD512/PCM 768k)Independent output mode display (Headphone / Pre-out / Bluetooth TX)

12. Do you need the “Output Mode Volume Memory” feature?

Absolutely needed: remembers previous volume when switching outputs, preventing sudden spikes or damage.Not needed: I prefer manual volume control.Keep volume synchronized across outputs.

13. Which Bluetooth TX pairing method do you prefer?

Auto-connect: The device automatically searches for and connects to the most recently paired headphonesManual confirmation: Confirm the connection via on-screen list (prevents connecting to other devices in the room)

14. Considering desktop space, what size is most suitable for H80?

Keep the current A80 size, compact and aesthetically pleasing.Slightly bigger is acceptable (e.g., for more ports or heat dissipation).Smaller is better, even if some ports are sacrificed.

15. For “l(fā)ate-night entertainment” scenarios, would you like the H80 to connect to two Bluetooth headphones simultaneously (dual-user mode)?

Essential: Often watch movies or play games with a partnerOccasional: Use it when friends come overNot necessary: I usually listen alone

Part 5: Purchase Intent
