What portable CD player do you recommend?

I will be travelling extensively this summer and would like to take my Sennheiser HD650's and Wheatfield tube headphone amp with me for the ride.

I need a portable CD player recommendation - preferably soemthing with a decent top-end.


i saw this a few weeks ago, maybe it will help.
iRiver makes great discman type players. Truly surprising and one with an optical out. Read review on headphones.com.
