I have received this device for a long time....Because this is a retail version that has been finalized, I was not interested in measuring it before. Especially considering that AKM’s chip factory has been burnt down...I think this machine will not be taken out for retail. If I measure and publish the data and finally it is not released... Isn't that a joke?It wasn't until I saw the pre-release promotion in the manufacturer's QQ Group that I confirmed that they would actually sell this device. So I connected it to my analyzer... and was shocked directly
What the hell is this? 4497 with 120SINAD?
This is the Spec of 4497:
I have measured many DACs based on 4497, most of which SINAD can’t even get close to the THD+N value of Spec.
Look at things first:
From the the craftsmanship of the case, D70s is even better than D90.The back cover is CNC processed, and the brand part of the front cover is also specially processed. It doesn't look so cheap anymore, well done.
This is the measurement result:
Topping D70s Dashboard4V(-1.5db on DAC)
Topping D70s Dashboard5V
What surprised me most is that the low frequency distortion increase of the previous AKM DAC disappeared... Almost -130 Multitone are crazy!

Asahi Kasei never die, it just burned down……
