Please recommend a portable audio devise for use with my Sennheiser HD-280 Pro headphones (64 Ohms). I want something that can drive these headphones loud.

I'm considering the Panasonic SLCT579V CD Player since I've read it has an analog amplifier. Would this work well or is there something better for under $100?

Edit:
I now have decided to also buy and use a portable amp, the PA2V2. So, what audio devise under $100 would work best with this amp and my HD280s?
