shouldn't the rca outputs at the back be a line level output with no volume control since it could be passed on to a speaker amp. If its volume controlled wouldn't that be double amping?

I can't really comment on "shouldn't", but from the PDF Owners Manual:
"The RCA phono line outputs are provided to connect the m9XX to your amplifier or speaker system. Use RCA interconnects to connect from the m9XX to the unbalanced line inputs of your power amplifier or powered speakers. These outputs follow the volume / mute control."
The m9XX is both a headphone amp and a pre-amp, so the functionality makes sense to me, and in fact is a welcome feature for many.

hmmm I see so in that case...if lets say its hooked up to a speaker amp. should the volume be set at maximum or is there a setting for optimum performance?

According to earlier comments here from Michael (Grace), you're going to want to set the m9XX volume to 90

IIRC, "unity gain" (neither attenuation nor amplification) is achieved with the volume set to 90 .

Unity gain with no amplification and no attenuation is volume setting "90" with no decimal point. Just to be clear!
