From a technical point of view, it should be the opposite.This. I also have my monoblock amplifiers behind my speakers and my equipment rack close to my listening position. My speaker cables are short and the balanced XLR cables between my preamp and the amps are relatively long.
From preamp to the amp, the signal is very low voltage and can suffer more from long cables than the high power signal coming out the power amp.
