Ribbon mic with cloudlifter and Y splitter cable, parasitic draw question

[Tanigumi]

I've been trying to split a ribbon mic, with cloudlifter, signal to 2 mic preamp channels. Let's call the channels "A" and "B". The idea is to keep "A" channel clean and send "B" to a spring reverb. The signal from the "Y" cable, at the preamp, is reducing "B" when I adjust "A" and vise versa.
Is this an impedance issue?
Other than using 2 mics, Is there a work around?
