XLR or RCA cables

In my system I have an Audible Illusions preamp that only accepts unbalanced (RCA)outputs while my Ayre amps accept only balanced (XLR) outputs. I am currently running 2 meter RCA interconnects with adapters at the amp but was wondering if running XLR cables with an adapter at the preamp would offer any improvement. Anyone have any thoughts on this? Thanks.

For a 3 meter run, there should be no difference.

I don't know if the adapter will double the voltage coming out from preamp. But let's say - if it does, then you will have "gain" in the system. With gain, you will have to go much lower on the volume knob. But again - just a theory - since I am not sure if adapters will double the voltage.

How can an adapter double the voltage unless it has a transformer or a powered amp? Either way, it will introduce more complexity and the possibility of imposing something other than voltage on what should be a transparent link.

Since most "volume knobs" are really just attenuators, there is no real advantage in higher output voltage unless the preamp outpput was inadequate.
