I am considering buying some headphones - probably Sennheiser 595's or 555's, and I plan to listen to uncompressed music files through my computer (.OGG). I have a laptop with a PCMCIA Creative Audigy 2 ZS card http://creative.com/products/product...&product=10769
Will this work well for driving my headphones, or do i need a separate amp? If I did get an amp, I would pay no more than 150 (not incl. shipping, will buy used) and so how would a 150 dollar amp perform compared to the sound card? Thanks


P.S. I also asked this question in HeadWize, but I need all the opinions I can get! $150 is a lot!
