connecting My Ruarks to pre outs

[nicknack35]

Hey all could someone tell me please how this works with pre out amps please to say my ruarks mr1's are connected to M/F V90 DAC via the 2 rca at the back of the DAC and then going to the Aux input of my speakers. Now if i get an headphone amp with pre outs how do you use your speakers with the DAC with it only having L and R RCA inputs at the back of the DAC. If pre out headphone Amps let you connect your active speakers then does the headphone amp become the amp for the speakers? and if so i dont think its a good idea could they blow lol
