I wish these devices weren't called 'Dac/Amp'. With no analog input, it doesn't qualify as an 'amp', in my mind - I want to be able to amplify an analog signal of my choice, and not be limited to whatever dac chip the maker has used in the box. Without that kind of flexibility, this is way overpriced IMO, $300 more than the Schiit Jotunheim or Audio-GD dac/amps that actually function as amplifiers, by providing analog inputs that bypass the internal dac chips.

The details don’t tell what sort of balanced output plug it uses. 2.5, Opticon 4.4, some other plug?

If you look at the pictures, it clearly shows XLR4.

I really, really, really would like to see some amps with (also) a 5 pin pro connector for Stax 009's

That would require a whole different amp technology that is typically not for 99% of the headphones out there. If that's what you're looking for, look for ones directly from Stax or KGHSSV/Mjolnir.

I see. Did not kwow that. I am happy with my headphone but I can never buy something good looking because of the 5pin

All the aesthetics of a coked out actor from the '80s. Who cares how it sounds when you're doing lines of coke off the top of it?

searching in chinese, there are quite a lot. DA9 5980rmb , DA10 6999rmb https://item.jd.com/11996804199.html
https://www.tmall.com/mlist/regular_CDNYiyAIlKE_m-5WBHxznw.html This review states that https://kknews.cc/zh-hk/digital/a8xjomg.html
https://kknews.cc/zh-hk/digital/nppnx32.html it is only around $6k rmb The marketing of chinese company are similar; they claim that the original price is high, but the discounted price is its Msrp.

All of this is moot. I have one of their earlier DAC/Amp models (the D100) which I like very much. However, recently it began to have problems, which I think are simple software problems involving the drivers for my amp and I have been unable to find anyone who can trouble shoot this problem. I've sent them a couple emails but never got an reply. So I called them and no one spoke English, so of course couldn't get help. They don't seem to have any support at all in the US. You're on your own. Good luck! I have to throw this unit away for what appears to be a very minor problem, but ultimately that's probably have to do. Bottom line: Yolong is a good manufacturer of hi-fi equipment, make sure you can get support for it before you buy. (And if you do find a source of support, please let met know. ( DorianLS@aol,.com ). Thanks.

I wonder how they come up with the specs. How can SNR be negative?

SNR can be expressed as the difference between power of signal in dB and the power of noise in dB. So -130 dB of SNR actually means that the signal is deeply buried in the noise. Who would knowingly advertise their product like that?

Mr. Wood, !it seems you are knowledgeable and using your good common sense. I believe you misunderstood the industry standards. is is exactly backwards from what you are asking. It’s meant that the noise is at a level 130 dB under the signal. That is actually a very good specifications that most manufacturers are entitled to feel very proud of disclosing. hope this helps clarify a little bit.

So many pics of the front and zero of the back. Anytime I look at any audio offering, I only care about what's on the back.

  1. Why are there no pictures of the back?
  2. Why is the power supply internal?

What do you think is wrong with internal supply? A good toroidal or O-type transformer is very good, better than a lousy switching supply (not that there are no good external supplies).

Interesting my thoughts when I was looking at the listing is 1. Why are there no pictures of the back! 2. Oh sweet it looks like it has a internal power supply maybe I should read more about this thing.
