Splitting signal from a DAC

I am in the process of purchasing a headphone amp that will be placed in proximity to my main system. My question is, to avoid the purchase of a second dac, can I place a set of splitter connections to the RCA outs of my BelCanto dac2 to run to my odyssey preamp and to the bottlehead or similar headphone amp. Would the signal degrade. Or not make a difference. When either amp is in operation the other would not be on. As always I appreciate your thoughts. Thanks, Dave
