Note: This article is based upon the article "Topping D90SE Review (Balanced DAC)" made by user amirm on the forum Audio Science Review and is printed here in partnership with Audio Science Review. The review was originally posted on June 15th, 2021.
This is a review and detailed measurements of the Topping D90SE flagship balanced USB DAC. It was sent to me by the company for testing and I believe costs US $899.
Topping D90SE DAC Measurements
Out of box output voltage is our standard 4 volts but there is also a setting to adjust that to 5 volt (see test of that later). Let's start with USB input and balanced XLR output:
Switching to RCA output, we naturally lose some performance:
Intermodulation distortion (really the noise aspect) sets a new benchmark:
Courtesy of resampling in ESS DAC, jitter is a forgotten word with either input:
Linearity locked in and ran so perfectly, I had to scratch my eyes to believe it:
The only puzzler was THD+N versus frequency:
Multitone is nailed so hard that you could almost hear it nail screaming from being hit so hard:
It is 3:00am but I had to stay up and post this review. It is not every day that every barrier we have seen in DACs gets shattered to new levels. We are seeing extreme attention to every aspect of this design to squeeze this much performance out of this ESS DAC. Just when we though the race was over, here comes one more over achiever! Those of you who have made it a hobby to upgrade the latest and greatest, here is another one for you!
At the risk of stating the very obvious, it is my absolute pleasure to recommend the Topping D90SE.
Note: this is a new product. If you are not an early adopter type of person, you may want others to go before you. My testing is focused on performance only, not reliability or functionality.
