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

I have a Classe 30 line stage preamp and a 70 amp. I am currently using the RCA outputs with a splitter to allow me to run stereo subs also. I would like to use both outputs from the preamp using balance cables to the amp and RCAs to the subs.

Is this possible? Thanks.

... 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!

... we don’t need balanced cables in the home very often, but in areas where you have a lot of Ethernet and HDMI cables running around they add some additional noise rejection ...

There's more to it than just that. If you're using components with truly balanced circuitry, you often get 6 dB greater output when using the balanced XLR connectors. Another way of looking at that gain is that for a given output level, you'll get 6 dB greater S/N when using balanced connections. That's a big deal.
