In past measurements we have confirmed that even discrete R2R can perform very well.

However, many devices using the same type of technology perform poorly, which is why I mentioned in my previous measurements that I instinctively hate discrete R2R.

Today we have ushered in such a unit.


A reader of my website sent me this unit and he wanted me to measure it.

(If you are from China, I believe that by seeing the photos, you can already understand what terrible things will happen later) ;););)

All the above measurement results indicate that this is a garbage.

Even more frightening is that the manufacturer is a liar

Here are the measurements published by the manufacturer:

My suggestion: you should Never Ever Forever consider this manufacturer's products.
You are definitly a audio-gd hater. I have put all your mislead opinions on ignore.

80% of the comments is just hate and blindness.

I have R1 R8 R7 (R7HE MK2 DI20HE incoming). They performs 100 times better than the best measure dacs you have here.

You are just keeping embarrasing yourself with this hate against AGD.

Nobody cares about your lonely hate, everybody know AGD will be so popular. It has already conquered(competitors) all the best hifi reviews.

Looks like your English translator is as reliable as an AGD DAC. ;)

Looking forward to seeing your ears-only ability to distinguish this from a $10 dongle. There's nothing like actual data and evidence to shut up the "haters." Make sure you're very explicit about outlining controls and level matching procedures.

I had the NFB 1 2014, it was worse than the Onkyo SE300 sound card I had and become a paper weight in my drawer since then.... now using the Holo Spring 2 and happy as ever, if you would like to get the NFB1 cheaply?

Can we see your measurements please? Or the statistics from your double-blind listening tests? Your OPINION of what you think the DAC sounds like is worthless without PROOF. And the only proof that has scientific validity comes from NUMBERS. Either competent measurements or, if you insist on using listening as your criteria, then you need statistics from well-conducted double-blind listening tests, preferably with a reasonable population size of test listeners. Opinions are NOT the same as scientifically demonstrated truth.

You know Wolf praises a lot of other local Chinese manufacturers who put plenty of thought and effort into their designs (and I don't mean just Topping SMSL etc, but also Holo audio, many others....) Audio-gd just isn't one of them. It's honestly sad to be so aggressive for getting called out on that.

One day? I thought the hype around Audio-gd went away at least a couple of years ago if not before. Even people like you have moved on to greener pastures.

Performance aside, has something changed about having to paypal the money to some individual to order something?

Why the parade of (bad) trolls for Audio-GD? Did I miss the memo?

Yeah, apparently they now request BTC / ETH transfers, so that they won't be required by Paypal to issue refunds to swindled dissatisfied customers.
At least if their DACs perform no better than those from the last century, they use state of the art payment methods.

Not as stupid as we thought they were.

Very odd to be so emotionally attached to a metal box that fails to perform the one job it has.

Audio-GD R8 has the third harmonic of a 1kHz tone well above -80dB, and it has lots and lots of other prominent distortion products. I wouldn't worry about it being audible, but a SOTA low distortion design it most definitely isn't.

Topping E70, a "dirty" op-amp based design, has all of its distortion products from a 1kHz tone well below -140dB, just saying...

I don't understand your argument about THD. The numbers are very much against you.

I've got another question: Did they finally hire an actual webmaster?
Apparently not:

Honestly, tho: I'm surprised by their progress in English! :p
What!? The design of their website actually looks fairly modern, don't you think so?

'Copyright(C) 2004 www.audio-gd.com All Rights Reserved'

Fair enough, maybe it was slightly more akin to websites from the '90s, but I'm definitely nitpicking here.
