Running receiver with no load - safe?

So far, I have connected the REW output directly to the sub or used the multichannel input for the sub on the back of the receiver. Both of these methods bypass the crossover used by the receiver. Someone suggested in another thread that the REW input could be connected to an AUX IN on the receiver and the mains disconnected to allow the sub to be isolated for measurement with the crossover rolloff.

I was under the impression that running a stereo amp with no load could possibly damage the unit! Is it safe to crank it up with no front speakers? My tx-ds575 is old, but I don't want to bury it yet by doing anything dumb.

Thanks a lot for the info. I'm sure that feeling of trepidation resulted from my dad fussing at me 25 years ago as I attempted to ruin all of his gear. (In the name of science, of course!)
My front door is open in anticipation of the big brown trucks arrival. With a wider assortment of cables and adapters, I should have a bit of fun with REW this weekend!
