Hi all, I have had the HD555 headphones from Sennheiser for some years now, and I really like them, so I'm thinking the HD650 ones would be a good upgrade. I bought the STX soundcard to go with my HD555's because I read plenty good reviews of it, and couldn't really figure out what external amp I would have to buy instead. I've not read a whole lot about audio at all, but I think the HD555's and the STX soundcard go well together, albeit I had to adjust the EQ quite a bit.
My simple question is this: Would it be alright to just plug the HD650's into the STX card, or will I have to buy an amp after all to get my money's worth? Thanks in advance.
(if it is of any relevance at all I use my HD555 to listen to music, primarily rock)
