Cons of using main XLR/Balanced outs for subwoofer?

I'm putting my system together for the first time in a new space with a new to me preamp and new speakers.

Signal Chain:
TT/Streamer
McIntosh C220
McIntosh MC7270
Ohm Walsh 4.4012

The 7270 does not offer balanced inputs.
The Ohms have active subs which offer balanced input.
The C220 has only one Balanced output for the Main Output. 

Is there any harm in using the main XLR output to send signal to the subwoofers, and using the 1, or 2 RCA output to send signal to the main drivers?

Thoughts?

Thanks

Yes. You'll unbalance the signal going to your main amps.
@atmasphere Can you explain why using the unbalanced RCA out for power amp and Balanced out for each subwoofer will cause a problem?

I also have the option of just using the RCA main and RCA 1,2 outs for each the drivers and the subs.
I thought it would be marginally advantageous to use the Balanced out for the subs since the run is >10ft.

@atmasphere is this true even using different outputs? Main(XLR) vs zone 1(RCA) vs zone 2 (RCA).

I will not be using the Main Balanced AND Main unbalanced outputs.
Instead, using Main Balanced out and a separate zone1/2 RCA out.

Not sure if this was well described in my post.
I appreciate your help.
