Pass F5 as a headphone amp?

[lorienblack]

Forgive what may be a silly question, but my technical knowledge didn't extend beyond a painting by numbers assembly of the F5.

I have purchased some Beyerdynamic T90 headphones (spec below) and was wondering if I can just wire directly from the RCA outs to a female headphone jack.

Many thanks for any pointers or clever suggestions involving resistors.
