Thank you.

What is your source? What are the headphones?

If you do not need an external amp, you'd probably benefit from the amp, as it should improve the sound quality.

My sound card is really starting to piss me off, so a DAC like the Modi used might have to be in the future. QQ, right?

OK, I'm not great at Audio so I will try and explain the best I can for you.
I use the CM Pulse R headphones. They are plugged into the onboard sound via 3.5mm jack. My onboard sound chip is realtek ALC892 HD codec with 2.0/5.1/7.1 support. The impedance on my headphones is rated at 50ohms according to the outer packaging.

Do I require an external amp to drive the headphones or is that impedance considered "easy to power" without anything additional?

Another thing, I am wanting to grab a Xonar D1 to increase audio potential. Good idea? Or do I still need an AMP to drive the headphones properly? Also, it worries me that these sound cards are from 2009 and they all seem to come with artificial EAX crap. Does this cause latency/input/stuttering in games even when disabled?

Thank you.

Any audio gear is near all our futures! Nothing wrong with justifying why you need to buy a DAC! biggrin.gif

Seriously though, I think a MODI or ODAC would be a good upgrade to a sound card!

But i can't say whether this price will stay that way because its still priced higher in other places €280~£240.

Thanks for clearing that up! Wow awesome deal you got there!

Looking at the pics you posted, It looks like the grills of the L2 are bigger compared to the L1, so it's now more of an open back than a closed back than before (if that makes sense).

Like you, I don't know a whole lot about audio, but I do know that generally speaking, you only really need an amp if the impedance of your headphones is over 64 ohms. I used some headphones very often (hours a day) for a quite a few months that were rated at exactly 64 ohms without an amp, and they sounded great. Now that I have DT770's which require an amp, I've tried out the other headphones with my new amp, and I can hardly notice a difference. If that means anything. tongue.gif

That does help.
Thank you,

Guy's, will the D1 beat the ALC 892? Also, do I have to have EAX enabled to have audio variation thing. This is what I mean by audio variation (listen when he moves the camera):

I think you don't need amp for anything <80 ohm, but then you also need to look at how sensitive the phones are.
So something like he-500 that are just like ~30 ohm(forgot the exact number ) but you need an amp for them.

It's normal for low impedance phones to sound similar with/without an amp, which just means your amp is transparent.

Transparent? In what context my I ask? Not needed? Also, could you input on the use of a D1 sound card please? I'm unsure if I should buy one.

Impedance is only part of a very very complex and annoying calculation. People come up with general 'rules', but most of them can easily be broken.

Honestly, your cooler master headphones were designed for computer gaming. They are far from audiophile grade. While the D1 is a great entry level amp/dac....it is just way to overkill for gaming headphones.

I would recommend looking for a used creative titanium HD or a used STX sound card wayyyyyyy before you invest much more money.
