Using power amps (for speakers) to power headphones. How? I don't understand it.

Someone told me I could use my McIntosh power amp to power headphones via XLR.  I don't understand how to properly match it so it can be done safely.  I have a McIntosh MC275 power amp and a C22 pre-amp.  Thank you in advance.

They probably meant the K1000s or the newer HE-6/5LEs.  These can be terminated with speaker leads.  Their need for amplification goes beyond what many normal headphone amps can produce.

The Mc275 has a set of 16 Ohms tap.  Perhaps I can use my Denon D7000 @ 25 Ohms on it?

Any power amp can be used to drive headphones with a simple resistor to limit current. This is also being discussed on another thread right now.

Try the headphone jacks on your C22.
