I got them today. I plugged them into the headphone out of the audio 4 dj just to see , and they sounded really low, almost worse then my $79 headset . So i went out of the rca out of audio 4 dj to the E9. Freakin Hell Yes best sound i have heard in along time.

thanks for all the info guys. I decided to get the Dt 990 and a E9 to start off with.

Well my Audio 4 DJ  is a 24/96k DAC. I just need a Headphone Amp for the full Potential of the DT990 Or D2000's right? Or should I just buy a new DAC like Essence SXT. Reason why i want to keep my Audio 4 DJ. Its the sound card for Traktor Scratch, and I record my vinyls into audacity without a...

So what would be best option for headphone amp with good sound signature?  I want to still keep my current sound card audio 4 dj. I use traktor , and record my vinyl with it to audacity. Would AH-D2000 be a better option?

Quote: A little confused by this answer. Although im leaning towards the D2000. the spec for a For a Fiio E9 headphone amp  is almost the same as my Audio 4 DJ.   Specs for E9 - Output power: 1W (16?); 80mW (600?) - Headphone Impedance Range:16? ~ 600? - SNR: ?100dB (A...

I only listen to vinyl recorded 24/96hz and compressed flac. and cds converted to flac. So i should be fine? or just get a amp to be sure?

I found the specs to the Headphone output , Im not very tech savy. Does this fit the bill to power the DT 990 600hm version?   Headphone Output Load Impedance 16 Ohms – 600 Ohms Maximum Output Level (100 Ohm load) 1,55 V RMS (load 100Ohm), 3,1V RMS (no load) SNR (weighted) 93 dBu THD+N...

I have been using ATH-M40S. I pretty much decided to upgrade the DT 990 600 Ohm version. I have a Audio DJ 4 from Native Instruments, which i use for my sound card. It has a headphone output with a volume control. Works great with my ATH-M40 because the ohms are low "60 ohms". Is the Audio 4...
