Hello guys. Finally the DA3 arrived. Load a few photos of the dac and the cable below, it comes with a single type-c to usb cable.
You can choose whether to use the balanced output or the non-balanced output. You can choose after how many seconds the display will turn off automatically. Also you can set the Rolloff on 3 different choices.
On the site there are drivers to make it go with Windows but it also works without, with the drivers supports DSD natively.
I took it to use it on OnePlus 3, I used a type-C to USB adapter on the phone and a cable that was the same as that supplied by SABAj but shorter to connect it to the dac. The connection does not give problems, no rustle, works with all the apps (spotify, power amp, tidal, netflix ...)
The DA3 has no internal battery, it turns on automatically when the OTG setting is activated on the phone, then it can be switched off and on by the central button.
Unfortunately, it uses a lot of battery, in fact, the phone really downloads quickly according to the house uses about 800mW, much more than the phone itself uses for daily operations. It drops 2/3 times faster in my case, for this reason I do not know if I will keep it ... Never being at home and often using the phone as a source is not very good for me.
I add that after 1 hour of listening to high volumes heats a bit '.. but nothing excessive, it is probably normal
AUDIO
I was very impressed, tried with Momentum in ear, Mometum over ear 2.0, Superlux HD 681 evo. I was not expecting this sound, tried with Sultans of swing Dires Straits and other songs of all genres. I have not tried it for a long time but what I can tell you is that of power it has enough, my headphones do not have a high impedance but it was enough to reach 20 for very high volumes ...
It gives a lot of three-dimensionality to the sound, the low frequencies have been attenuated on the mometum in ear but improved a lot in quality ... much drier and more precise bass. The sound of the guitar in Romeo And Juliet is really great. Overall, the sound improves a lot. Power has it .. Compared to Fiio Q1 mkii is another planet, the sound is more precise and clearer. I call it more "open".
If you want information or curiosity I am available to give you information to clarify any doubts
Too bad for the excessive consumption of battery on mobile phones, in my opinion should be bought for use with PCs or laptops but not mobile phones or other sources with small batteries
Tomorrow I upload the photos, including photos on the scale to see the precise weight.
ps. excuse me for my english. I use google translate. If you don't understand anything ask me for questions.
