I've been spending the last weeks trying to decide on a setup for gaming audio.
I recently got the Astro A40 + MixAMP Pro 2013 bundle, but due to faulty hardware and firmware, I'm returning it.
I'm not an audiophile. I've previously used a Steelseries Siberia V2 headset with internal soundcard from my mobo.
My main use for this setup is 80% gaming with voicecomms(mainly FPS, which is why I need good directional sound), and 20% music/movies. Again, I use Spotify for music, not FLAC.
For a headset I've decided to go for the Beyerdynamics DT 770 Pro 80's with a clip-on microphone.
To go along with this, I've chosen the Creative Xi-Fi Titanium HD sound card. I prefer this over the STX due to support, drivers, software to easier switch between presets and reviews. It appears to have a cutting edge over the STX for directional gaming. It also seems to have better shielding,
Now to my question:
From what I can see, the Titanium HD has a built-in amp with 300 ohm.
This means I can power the DT 770 Pro 80's just fine(even the 250ohm, but I see no reason for getting them).
However, many claim that I need to use an external amp for the DT 770's even with the Titanium HD.
Could someone please clarify this and help me understand this?
Why would I need an external amp when the sound card goes up to 300 ohm?
As a bit of extra information(not sure if relevant); I know the amp on the Titanium HD can be swapped, but I'm never going to do this, since I'm.. realistic.
Thanks in advance for any advice you can offer.
