There are vintage receivers that put some serious power out the headphone jack and I'm sure there are a few newer AVR's that are better than some of the cheaper/mid headphone amps.

Not sure about this model but most modern Home theater receivers have  headphone outputs that don't actually use the amp that powers the speaker connections on the back.  Usually the headphone out has its own crappy amp that is inferior to a $200 desktop headphone amp.  Connecting your headphones to the speaker leads on the back is a whole different story....


I know some older receivers have great headphone outputs
