Go browse around Head-Fi. Lots there.
I run a Sonic Frontiers Line 3 that Bill Thalmman did his magic (and it is magic) and retubed it with NOS Siemens CCAs and E88CCs. I love this preamp - this mod/retube took a very good preamp and made it great.
The Line 3 has a SE headphone jack which I used for a while. After reading tons and exchanging e-mails with Head-Fi members, I auditioned a Rudistor RPX-33 (now the RPX-35 due to a few minor updates), a dedicated, SS, SE head phone amp. I run it from the tape outs on my preamp.
The unit never went back. The improvement over the Line 3 head phone jack is immense.
There are several very prominent, quality head phone amp manufacturers (SS and tube) out there. It tends to be kinda boutique - even more so than big rig hi-fi.
Good luck.
