There are freely available tube type headphone amplifier schematics available that do not require an output transformer. However, rather than drive the headphones with a tube directly, a far superior method is to use a MOSFET in source-follower configuration (a buffer). Buffers add no tonal qualities. Circuits which add gain can and do affect sound quality. A buffer does not. Using the MOSFET means the circuit driving it does not get loaded down at all, and there is plenty of current available to drive the cans, whether they be low impedance or high.
