Mark Levinson 360S & use of both RCA and balanced

I would like to use both the balanced and single-ended outputs from my Levinson 360S. The reason is that I want connect the balanced interconnects to my main preamp while using the single-ended interconnects to feed my Melos SHA-1 headphone amp. Does anyone out there know if this is going to work without causing any problems?

Thanks in advance for any input.
