generally not recommendable to hook up a fully balanced phono system

If the phono preamp and line stage preamp are truly fully balanced (differential) amplifiers, then it won't matter. That's the whole point of using balanced amplification.
If the "balanced" preamp uses op-amps at its input and doesn't itself operate in differential mode, then using RCA connectors might be a compromise.
