Splitting the channel will work. I'm doing it because I use a tripath amp. You will see a slight lessining in gain.
I'm using a Lightspeed Attenuator and lost less than one hour of gain on the volume knob.
If you listen at 11 o'clock before the split. You might have to go to 12 o'clock after the split.
I didn't notice any degradation in dynamics or attack, just in gain.
I know every system is different, so it might be different in your system.
Good luck and let us know how it works out for you.
