In this thread ，discuss the upcoming D90 DAC from Topping.

I reply: I will measure this unit.

Stop talking nonsense, look at the equipment first!

This is a compact unit. The overall size and weight are very friendly (especially considering it has so many input and output interfaces).

Of course, from the "Hifi" point of view, the compact size and densely arranged interfaces will bring some troubles --- those "Hifi cable fans" like to use a variety of egg-like size wire and connectors ...

It's great! They basically do what they claim! (The 122dbSINAD previously released was A-weighted, and I also got similar results after adding A-weighted)

All of the above looks perfect and seems to deserve a high recommendation.

but! There may be some bugs ... I'm trying to contact the manufacturer, but there is no result yet.

Anyway, weird measurement results for the device at hand must be posted:





Update：



They fixed the problem of AES interface J-Test! !! !!

After communicating with Topping, I decided to wait for their "retail version".Then, I got this "retail" today.This machine was borrowed from Topping. They provided the machine and shipped it to me. I will be responsible for the cost of shipping back after taking the measurements here.The surface feel is average and lacks high-level feel. But considering that it is likely to be cheaper. This is not a problem.None of the above is actually my main concern. The key is: What about performance? How about performance?Here are the measurement results:Dashboard 48K:Some friends advised me: a fast measurement result of 44.1K sampling rate should be provided at the same time:Of course, after the event of the SMSL M500, I may need to find an opportunity to re-measure the samples on the market sometime in the future. But anyway, this unit I have is great!Here are some other routine measurements:
