Using both balanced and single ended outputs at the same time?

... at the levels we are typically talking about, 90 dB signal to noise, sure, I can measure 90 vs. 96, but I can't hear it.

Some people like the addition of noise in their systems, feeling it adds a sense of "spaciousness." Suit yourself!

I did it successfully with a Classe CP35 and Six...long ago ...

I have a BHK pre with both balanced & RCA out. The BHK instructions state one of the uses for the RCA’s out we’re Subs. The only issue is the balanced out was +6db, as @cleeds said over the RCA out so had to adjust the sub volume up to compensate. 

Well you always have to adjust the sub (s) volume.  This is not a negative nor an issue.

On my Krell Illusion and Krell 300xd they both have Balanced outputs and Rca outputs along with inputs So I use high quality locking xlr connection between units.
