Headphone amp for Grado 125's ???


My "private, in the leather chair, by the fireplace, with a single malt scotch" listening station consists of Grado 125 headphones plugged directly into the headphone socket of a surprisingly good sounding Tivoli Model CD player (please don't laugh....it really sounds way better that I would have imagined). A RadioShack adapter fits in between the 1/4" plug of the Grados and the 1/8" socket of the Tivoli.
I'm willing to spend ~$200 to improve the quality of this nice little set-up.......What are your suggestions for a headphone amplifier, and would one really make an appreciable difference ? You can see from clicking on my "system" to see my main rig (in a different part of the house) to get an idea of how I like things to sound.
Thanks a lot.

Have you ever plugged your cans into the Rogue? I know that's not the room you use them in, but just wondering.
No.............I have not. But, since you've asked, I will try the Grado 125's plugged into my Rogue, and I will let you know. Meanwhile, I've been extremely happy up in my livingroom in front of the fireplace with my new headphone set-up, and there seems to be some very nice synergy between the Grado 125's, the Project Headbox II, and the Tivoli Model CD. My serious listening is still done in front of my Vandersteens, but the "cans set-up" is a fun alternative with my dogs and me in a relaxing state of mind.
One day later,....... Well, I tried my Grado 125's plugged directly into the Rogue Audio Cronus, and, WOW !!! Seems like a pretty perfect match. Eva Cassidy sounded incredible !
