Splitter on gpa 555!pre amp output

I have had two bridged Adcom gfa 555s since 1989 into 4 speakers. Is it safe to buy a one into two splitter for the left and right outputs on my pre-amp so I could run each amp independently for each pair of speakers?

If your preamp output impedance is 1kohm or lower it should be fine, otherwise the low frequency output will reduced.
