OH POO!!!

"One can use the t-Amp as headphone amp, with caution: first of all,
there's no output jack so one has to adapt the speakers posts to a female
jack. Secondly, frequency response rises at the highs as the load
increases. Tripath claims the output filter should be designed to make the
amp linear till 16 ohms. Hence, I'd suggest using extremely low impedance
headphones or ask a techinician to modify the output filter settings.
Finally, the T-Amp uses distinct L-R grounds, while headphone normally
connect these together. This can destroy the T-Amp."

BAH!
