Sure. But you should not split the output from your DAC, or else volume level and fidelity decrease, if I am not mistaken. You would have to have one device plugged into the splitter at a time, making the splitter redundant. Alternatively, you could just plug the speakers into the Solo with a 1/4" adapter plug and use your Solo as preamp, but you cannot have both headphones and speakers plugged in at the same time without a splitter then if you have both plugged in to a splitter, sound suffers, and its the same thing, lol.
Edit: Is your Centrance the DACport or DACmini CX?
For the DACmini, you can just plug the speakers into the headphone output while using the rear line-out for your Solo, so you use the Centrance for vulme control.
