I am interested to buy this one but what is its difference compared to the E12?
Sure can, I use this with a 770 250Ohm primarily.
actually i saw a seller sell dt990 600 ohm with bundle fiio A5 for $279.
for the price, i think that's a great deal. but i'm not sure it will handle hungry cans like dt990 600 ohm, since i don't know how the calculation is. i am noob
some say high impendance is hard to drive, some say low impendance low sensitivity is hard to drive
Impedance is not that close related to drive.
High impedance cans have really sensitive drivers, while low impedance have less sensitive drivers (harder to move)
Either approach has the same potential to sound good.
About the power required, it literally depends on the headphone. Ultrasone DJ1P is way harder to drive than Dj1, but you will drive both with the volume pot before 12 o'clock from A5 + high gain.
xo will fiio A5 drive dt990 600 ohm?
Yes it will.
Unless you are a stone cold power user listening at 95+dB all the time then you will be fine. And your ears will be more fine.
Hello,
I started head fi with DT 770 250 ohm with Fiio A5 set up. If i don't open the high gain on Fiio A5, the sound of headphone is not loud enough even at highest volume of A5. Is this a normal situation?

@Dobrescu George if i am correct, low gain of fiio A5 gives you 0 db improvements of sound loudness level, so that setting is just for driving the headphone, it should be? Since i am new at all this head fi thing i expected a good volume gain or loudness when i just plugin the amp to the headphone while it is on low gain but there isn't. So i am a little bit disappointed. Later if i open high gain i don't hear any distortion of sound and generally speaking for the most of tracks i use 11-12 o'clock with amp volume button. When i raise it to 2-3 o'clock i got that loudness for sure but it is kinda different from my cheap headphones and i believe that is because the characteristics of dt 770 250. since dt 770 250 is my first entery level headphone i think i shouldn't expect loudness or much volume gain, but again i am not sure. Because there aren't a lot of equipments around me right now. And i will try to be in a silent place while listening, thank you, does it effect the headphone that much even it is closed one?
@shuto77 Yes the source has highest volume. When i first arange this setup, i underestimate the importance of dac. And i didn't think dac will improve sound loudness and quality that much. For instance i use iphone SE with these and it is simply the worst audio output i have ever seen, even my onboard sound card is better. "Sidenote: Don't buy i phone se if you want to listen from it, definetely the worst choice as a dac. " Later i used an ipod from 2010 and the sound improvement was impressive. So i decided to add a dac to this set up and i consider to buy USB dac with ES9018k2m. I wish this dac would give what i want.
The main question is when i just plugin my headphone to A5 at low gain. I don't hear any sound improvements that much. What should i wait from A5 if it's setting is "bass->offf" and "gain->low"? What should i hear? What should be different? Thank you.
I've been wondering about this for a while now, will the sound quality be affected if you use long cables with say impedance 0.9 - 0.5 ranges from the dac lineout into the A5 or any other amp? i measured the resistance on the fiio ic and its .02 <-- damn...
