HELP: Amp suggestion for dt 990 pro

post #1 of 9
Thread Starter 
Hello all,
Recently, I've decided upon acquiring a pair of beyerdynamic dt 990 pro 250 ohms to join my 770 pros. Currently, I run all audio either out of my nexus 7 razor or HTC one m7 which are both amped by my e11. While I relalize there are a couple threads that have already asked this question they all got cluttered by others asking different questions and what not, so, can someone please give me a definitive answer on how well my e11 will drive the 990s and should I need to upgrade, what do you suggest (keeping in mind that an upgrade to an amp that costs more than the cans themseleves is unreasonable).
Thanks in advance.

The FiiO E11 will drive the DT990 Pro 250-Ohm headphones to a decent volume with the E11's volume knob at around 40%.

but that's what I have it at when driving the 770s so how can that be possible?

I'm guessing it's because the DT770 and DT990 use the same or almost the same diaphragms.

while that may be true the impedance between the two is more than triple.

I'm just guessing, but I would assume the DT770 Pro 80-Ohm is a tweaked DT770 Pro 250-Ohm.

 

I own 7 Beyerdynamic headphones

DT770 Pro 80-Ohm, DT770 Pro 250-Ohm

DT880 Pro 250-Ohm, DT880 Premium 600-Ohm

DT990 Pro 250-ohm, DT990 Premium 600-Ohm

T70 250-Ohm.

And I've plugged several of these headphones into my FiiO E11 (about a year or two ago).

Maybe the FiiO's volume knob was at 50%, with the 250-Ohm headphones.

with the volume knob almost on max, it will drive the 600-Ohm headphones.

fantastic. Thank you so much for your help!

DT990s can go pretty loud out of a Fiio E11 with modern music (yes, 50% probably). If you usually listen to audiophile recordings with high dynamic range, you could find yourself cranking up the volume (90% or even more depending on the recording)

 

That said, as you might guess, loud just means loud, not necessarily clear or full sounding. In my experience, even my Fiio E07K (or E10) (USB DAC/Amp) fail to show the full potential of DT990s.


By comparison, when plugged into the headphone out of my Yamaha A-S500, they sound noticeably more open and realistic. This is quite a controversial topic, I'm just talking of my own personal experience (and using well recorded music).

 

Talking subjectively, using DT990s with Fiio Amp you get the sound of good headphones, and when you raise the volume you start feeling uncomfortable.

On the other hand, when plugged into the A-S500 and raising the volume, the room is somewhat filled with sound, loud and big but harmless. The overall experience is definitely closer to listening to the same track with nice speakers in a proper room.

 

Comparing the price of a high quality amp with the price of DT990s (Pro version) is not fair, I think. DT990s are great contenders under 400 dollars, that you can find at 150 if you don't mind getting the Pro instead of the Premium version. Price doesn't mean so much this days.

 

You could drive DT990s with a Fiio E11, and they'll sound good and also loud most of the times, but I guess you won't regret buying a better amp in the future to pair with your 990s. (Something like O2 Amp or Schiit Magni should do the trick I guess - I couldn't tried them yet, but I've read good things about them)

 

Best Luck!

thank you for your input. I definitely planned on upgrading amps eventually, just was hoping I could drive the 990s and the upgrade would be a decision rather than a requisite.
