Let's hope for the best. As I have bought 5-6 Topping products, 4 of which I use myself every day for the last 4-5 years, I am a bit skeptical because they always seem to send me golden samples, which of course is cheating.
Thanks for the review. It complements NTTY's review nicely.
Loving my DX1 II here: impressive little device!

its not really possible to build a golden sample with modern equipment , will the golden sample have a separate manufacturing process and logistics chain .
If the components and PCB are the same your pretty much done ? what fractions of a dB would you get be selecting a special one . performance are often set by NFB loops .
In the old days component values had a bigger influence over the result now you string IC's together with a high level of feedback .
More focus on PCB layout etc .
A tube design with low feedback and transformers involved is prime for building a golden sample ! not a multilayer pcb with IC's ?
Toppings problems are usually QC and support issues . These can explain the price , a god organisations costs real money .
QC can be a serious issue with the provenance of components etc ? what are your supplier of op amps etc ?
To establish if this is the case the product needs to sampled and measured over years from multiple production batches ?
We have two samples that looks similar Amir and NTTY has measured . So the basic product seems legit
but who knows about the future .

I like how it's basically perfect in all measurements wise (including available power) & also contains PEQ & whilst being good value - so much so that I thought about buying one & then I realised I need to have 7.1 channels available to the OS sometimes, so I will have to stick with my SoundblasterX G6 DAC.
If you mean the ground loop I believe it is caused by measuring equipment and would not apply to a home audio system. Not that we should be using unbalanced signal anyway when a higher performing and immune to ground loops balanced signal is right there.
Didn't see an analog input anywhere, or mentioned in the user's manual so what would the ADC be useful for?
The front jack takes a headphone and includes microphone for computer/gaming use.

Any penalty for DSP on vs. off?
@NTTY looked at it.
Topping DX1 II DAC & HP Amp Review
Hello everyone, This is a review and measurements of the Topping DX1 II Dac and headphone amplifier. I bought it from Topping site and received it rapidly. I got it for around 120$. Topping DX1 II - Presentation This little device acts as a DAC (USB or Optical input), with line level...

Activating it didn't seem change anything, but he noted he had not full evaluated it.

Since this does have mic input from the 3.5mm jack, what would does the unbalanced power look like? Seems using this with a headset (like my pc38x) is one of its intended use cases. It feels like they threw everything except the kitchen sink into this little guy!
Something like this could work with it, if power is an issue for anyone: https://amzn.eu/d/0i0sFtOV

The DAC also comes with a USB C to C cable and USB-C provides more power.
USB 2.0 USB-A power: 2.5w
USB 3.0 USB-A power: 4.5w
USB 3.0 USB-C power: 15w
Mine is connected with 3.0 USB-A
But obviously that could help if connected to a tablet or something..

Apart from the complete mess with 44.1kHz (Fosi Merak CD-player does not work at all) it now works fine

Hello Amir,
I really appreciate your fantastic job, and I always read with real interest every new test, but I am wondering why so many DAC and hedaphones amp... I suppose very few people are interested in Headphones amp, I would like to see more speaker tests, amplifier tests, and so on.
Anyway always a pleasure to see your job.
Best regards.
