Silver to Preamp & Copper to Amp?

I've heard this described as a logical setup. Something about preserving the details from the source, and then being more controlled and true to the base as you feed the power amp.

I'm looking to run AQ Diamond X3 (balanced) from DAC to my BAT preamp, and then AQ Anaconda to my Krell amp. However, my cable lengths would make it much easier to do the copper Anaconda to the pre and the silver DiamondX3 to the amp. As I prepare, any thoughts on whether I'm OK either way?

Thx,
