I have the HE-500 which I am using as my PC headphones. Theyre connected to a 9 year old PPA amp, and that has RCA outputs. Right now I am using a RCA to mini plug and thats going to my Xfi Titanium HD sound card, which I believe has its own amp for mini input. This sound card also has RCA...

I have a PPA amp I bought in sometime in 2004 that seems to still work fine and was wondering if this should be adequate for the HE-500 (has not arrived yet)? Im using the PPA with the K701 at the moment and it sounds fine though since its the only amp I have had I have no idea what I might be...

Which amp would you recommend for around $250(or less : )
