I don't find the jitter values that great when compared to the manufacturer's specifications. The image is from the Gustard x16, and it looks almost identical!

Is there a possibility to set the DAC in direct DSD mode? The newer A18 MQA has this option in the settings. That shouldn't be a big problem for the manufacturer. As I can see in the schematic of the AK4499, a bit needs to be set

According to the datasheet, the Mornsun regulator has a maximum noise of 200mV peak. However, when I measured the output of the HS02, the values were under 20mV noise. The values did not improve even when an external power supply was connected to the HS02. I could describe how the sun rises in...

It is important to recognize that science is a constantly evolving discipline based on continuous research and verification. While it is legitimate to question certain aspects of science, it is unreasonable and unproductive to reject the entire discipline. Instead, we should strive to critically...

What could be the reasons for the ban….questioning all sound influencing factors would be sad. It is only through such people that science is where it is now!

The HS02 has an isolated DC-DC controller from Mornsun installed. Accordingly, the 5V on the isolated side does not look nice. I wonder if Topping has tried how it sounds without this crappy regulator. I don't think that only measurement factors play a role, or do they?

Hello, have you tried supplying the HS02 with a clean voltage? It seems like an external power supply is still going through the DC-DC converter in the HS02! Regards, Gio.

i have often read that without the tweeter protection cover the frequency response will become slightly smoother. Is there any measurment that will be verify this statement?

It is not about opinions but about audio science. Therefore, the twin-tone imd measurement should not be missing.

Rca Output measurment?

I forgot..... for audiosciencereview readers a process-heavy audio player is the best

Have you tried the other connections or only usb?

I have the a18. The first impression is positive: workmanship, feeling of value, sound are good. I can only compare it to the Topping d50, and in my opinion the a18 is the better one. I think the messuring results speak for themselves. Incl. tax customs duty and shippment with dhl express I...

Audible?

For this price the dac seems to be quite good. What about the thermal stability?

Hi @WolfX-700 can you do jitter measurement with coax input please?

Very interesting DAC. If the published measurements will be confirmed it is a real strong product on the market.
