Topping D10 or D30 for raw performance? Which one is better? I don't mind for input and features, just raw performance.

I have both. I got the D30 first but I got the D10 for the optical out to try and solve a usb clicking and popping issue.

To my ears they are 95% identical but the D30 is slightly warmer. This is splitting hairs. Its like taking 10% of the cheese off a cheese burger and claiming it tastes different.

Buy either be happy.

Thank you! Which one is better on paper? Which is measuring better?

I believe the D30 measures a bit better but Amir used two different analyzers. The DAC on the D30 is much older, classic Cirrus Logic DAC from the early 2000s. The ESS DAC in the D10 is much newer but I believe has slightly worse specs. I could be wrong. Either way they are very similar products.

The D30 uses external power while the D10 is powered by USB power.

Hmm I think DAC from D30 has slightly better specs.

Advantages and disadvantages of using external powering DAC or USB? In terms of performance. I do not mind if there is one brick more.

It is separate from your PC power so in theory if you have it in a good plug it would be isolated from any audible issues arising from dirty usb power. In practice the DAC filters the power anyway. I have all my audio stuff plugged into a power conditioner, dunno if it makes a difference but its nice to have. People don't talk about power conditioners like they did in the mid 2000s.

Thank you for all the work done! As I started my googling into the amazing world of DACs, I kept running into comprehensive articles from ASR. I have a worry though: ASR is probably one of the driving forces behind the popularity of Topping DACs. But I also read the components are changed over time. Is it conceivable that what was measured is now very different from what can be purchased now?

I got this vintage DAC after I was having some RFI interference issues with my D50s and Modi 3. It was not the fault of the DAC, it is just that I live very close to an airport and a military base, so a lot of the equipment picks up their radar blips. Happy to report that the D30 is absolutely RFI interference free. Honestly, it sounds great as well, with extremely low noise floor. Nice high output voltage and channel matching (within 0.002 Vrms). My D50S had a 2% variation between the channels (0.035Vrms) which I did not think was acceptable.

At this point, I am actually leaning towards keeping this as my main DAC. One thing that gives me some niggling concerns is the fact that the intermodulation distortion on the USB input has never been measured on this DAC using the most modern approach, and the SPDIF measurement showed IMD on a high side. Amir or WolfX-700, is there a chance that you may run this test for the USB/Toslink input? I would love to see how it compares to the Modi 3 or OL Dac for example.
