I am a newbie to the site, but have been lurking for the last few days doing research on a decent gaming headset. I finally settled on the PC350s (modded, of course), and am just wondering if my Xonar is up to the challenge.
I have searched this site and many others, and have found "yes" to be the modal answer, but some people do say no.
I tried finding out the official listing for output impedance from Asus, but came up with nought. However, anecdotal evidence from several threads suggests that the Xonar is up to the 150 ohms of the 350s. I have seen people say their amp(s) made no difference, even people using my exact card and the same cans, and have also seen people say their D2X can drive their 250 ohm cans. Others have said you need an amp, at least just to get the most out of them.
The resident audiophile on Guru3D (My first ever tech site *sniff* So many memories), Rob, says I will need an amp, and he tends to be right about these things. But with the majority of people disagreeing with him, I really have no idea.
150 sounds like many an ohm, and I don't think the Xonar has any kind of amp, so I am a little sceptical.
P.S. I have thrown in a poll for easy counting :)
