Do I need an amp for Beyerdynamic DT990 Pro 250?

post #1 of 14
Thread Starter 
So I am buying these to use for my computer. My motherboard is an Asus M5A99fx Pro, and I have no idea what it has in it for DAC or amp although it seems really good and I would think it should cause its a pretty new mobo, but then again my current headphones (Ultrasone DJ1) are easy to drive anyways. If anyone can shed some light on the mobo sound specs that would be awesome.
So can I drive these? Or do I need an amp. I already have an idea of the amp I want, Schiit Magni as I've read good reviews and it is the most I can spend on an amp.
Suggestions are appreciated, thanks smily_headphones1.gif

Creative Labs Sound Blaster Z (SB1500, retail box) sound card ,Newegg has it for $74.99, with free shipping.

Should resolve your issue.

I guess the SB1502 is the OEM version, where as the SB1500 comes in a retail box (with mic and EMI shield)

I believe the SB1502 does not comes with an EMI shield or microphone.

The SB1500 on sale is only $18 more then the OEM version, normally the retail version would be $42 more.

Personally I would prefer to get the one with the EMI shield.

So I went with the cheaper version... I received it yesterday, and I disabled and completely uninstalled the on-board sound stuff and installed the Sound Blaster Z. Everything was good at first, sound was perfect, it drives the DT990s nicely (:

But then today I notice when I start games (Far Cry 3 especially) I get a buzzing noise in the headphones that seems to change depending on how much work the graphics card is doing. Tried restarting, taking the card out and putting back in, unplugging/plugging everything, etc. and the sound still persists when I start a game.

I have read around and people were saying that sound cards and graphics cards interfere a lot... and that an EMI shield can help. Man now I regret not paying the extra $18 hahaha.

So... what should I do? Return it and try the one with the EMI shield and see if it fixes it? Just stay with on-board audio and get an amp?

Return and pay the extra $18.

So now the sale is over and the one with the EMI shield is $104. Do you still recommend getting that instead of an amp like the Magni or maybe the O2?

I would recommend the shielded one. Are you using the front panel for your headphones or the dedicated headphone jack in the back?

Oh, the front one. I guess I should have tried the back too huh?

Yes. Shorter signal path equals less chance of interference.

Well the front panel doesn't use the amp, and most computer's front panels aren't grounded properly and are very noisy.  I recommend just using a 3.5mm extension cable for your headphones.

The headphone amplifier built into the SB-Z works with the front panel headphone jack.
