I just purchased a pair of Sennheiser HD 555s and I listen to music and watch movies on my pc. I was wondering if anyone has any advice on the best way to get the most out of them. I was thinking of getting an amp from the headroom, looking at the total bit head. Also considering a Onkyo TX-Sr507.
Any comments or suggestions on which way to go, or any other suggestions that you may have.

Thank you
