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

Ralph said "So if you have a balanced output on the preamp and a single-ended input for the sub, the ISO-MAX Jensen box is the elegant solution". 

Question/clarification...since the ISO-Max transformer has a single ended input and a single ended output, are you using something like this Neutrik adapter to go from preamp balanced out to transformer rca input?
