First amp.


Hi everyone!

I'm starting my adventure with high quality audio, but since i am a college student, i just don't have enough money to get a true hi-fi. I'm looking for a decent amp, but don't want to make a newbie mistake, which i would later regret :] Just a really quick question to experts: which of the following ones would you choose?
Denon PMA-700AE
Onkyo A-9155
Pioneer A-10-S
Pioneer A-20-S
Denon PMA-520AE
