DAC break-in question

I'm not wanting to debate if break-in is real or not. 

Can I just stream to a DAC and keep the amplifier off (the Dac is running and showing the sample rates, etc)? Or does a signal need to be getting to the actual amplifier?

My amp is Class A and I do not want to leave it running. However, I don't want to dig into my house ceiling speaker system (a real pain).

Thanks in advance
