CD player feeding two preamplifiers at the same time

Hi again -

I need to know if this is possible or will create an epic explosion.

What I would like to do is use my source (Levinson 5101) CD player the following way:

XLR outputs into the BHK Preamp (for most everyday music)
RCA outputs into the Bryston BP26 Preamp (for very old mono recordings (40’s & 50’s)

All while using a XLR output switching device to direct the preamp outputs to the monoblocks/speakers…

Any thoughts?
