Stepped it up a notch and ordered a set that's coming this week.   Will be back to report experience.

Did some quick research and found out that the amplifier on the ZXR is 80mW. I think based on that, I should consider getting the 250ohm set instead.   http://forums.creative.com/showthread.php?t=699412

600ohm on a ZXR soundcard vs. 250 ohm on the same sound card - which would you go with?   I am leaning on the 250 for the price and since I could use them on other devices without an amp (obviously would want one in those cases)

Thanks for the quick reply!   I am using a Soundblaster ZXR currently which is supposed to be able to power up to 600 ohm. I do game but the reason I am switching is for music. My brother brought a set of ATH AD900 which just sounded much better.

Recently picked up a Soundblaster ZXR and was disappointed when I plugged in my Sennheiser PC350SE headphones when comparing them to a set of open air ath ad900 headphones.   So I need some input on a new headset or set of headphones I can use that would take advantage of this card. I am...

I have these headphones with the Soundblaster ZXR:    ATH-AD900  Audio-Technica  Sennheiser PC350 SE   These are plugged in through the ACM module and what I have noticed is that the Audio-technica headphones sound better on an Ipod and on my PC when compared to the PC350 headphones...
