Now the the pound is cheap, I wonder whether they will sell for less money over seas. I bet it's a good value either way.

Can you easily remove the lid?

With 1KHz @0dBFS applied, has the 2nd harmonic around-130dB and the 3rd one around -112dB, hence seems to measure better than the best (OPPO UDP-205), at least in regard with the below graphs:

It would have a SINAD of 106 though per notation on the graph. Then again their data is for 96 kHz sampling which I don't measure at (worsens SINAD).

Different tools, different results, like always...

John Atkinson's measurements from Stereophile:

seems like way too much money for 18 bit linearity

Actually I like John Atkinson's review for this DAC. He found those multiples of 44.1KHz with some "spurious enharmonic tones that are much higher in level than the sidebands", but definitely inaudible at those low levels, while the multiples of 48KHz are measuring perfect. Well, the -90dB signal could be a bit cleaner actually. I think it measures pretty well after all...though this DAC looks more expensive than it's performance and its features, I agree on this one for sure (at least I won't pay such money).

However, comparing this unit with Khadas or Topping D50 is similar with the comparison done by Benchmark Audio with Porsche vs. Cadillac: https://benchmarkmedia.com/blogs/application_notes/124929287-how-should-i-buy-an-audio-system.
