We are preparing to adopt the universal standard gain of 6dB. Generally speaking, 6dB should be compatible with most devices now, right? Or is there any special case where different gain levels are very important to you?

We have a similar product with almost the same functionality as you mentioned, but the DAC chip uses AK4493S.

Yes, it's possible. If you don't need so many interfaces with ZD3, you can also purchase our ZP3 directly. ZP3 has HPF function and two adjustable modes (80 and 120Hz).

At present, it is possible to accommodate two ZA3s.

Yes, we plan not to use a potentiometer, but we do design a balance adjustment function.

Thank you for your suggestion. We are also considering whether to add a separate power button. We would like to ask why it is necessary to maintain the toggle switch of the power input port at the back since the product's switch status can be controlled at the front? Regarding the understanding...

I agree with your point of view. The information on this display screen is just a randomly selected display content. In fact, we may place the volume at the most important position. I would like to ask if you have any suggestions about the content displayed on the screen. If possible, please...

We are also considering using a power socket without a switch, similar to the picture below. We are also considering using a linear power supply, but the cost needs to increase. I wonder which type of power supply do you prefer?

You can also turn off LPF, which means you have an additional RCA input port and can connect an additional audio source device.

Our current definition of knob operation is as follows: 1. Press and hold for 2 seconds to shut down 2. Click: Power on 3. Clockwise/counterclockwise rotation: increase/decrease volume 4. Click: Enter the secondary menu Can you accept the above operation? Do we still need a separate switch button?

I don't quite understand what you mean. Besides static volume, input mode, and sampling rate, do you want to display anything else? Is it convenient to explain in detail?

May I ask which products the two OPT inputs are used to connect to?

Yes, it is expected to be launched in July. We have already started preparing for production.

I would like to ask if everyone also wants to support SUB out output when RCA input? What devices are commonly used for audio sources?

Sorry, we would like to ask why you want USB power supply? UFO202 should support both MM/MC player inputs, right? Do you think there are any other bad features besides UFO202 that are not very attractive?
