That is what XLR is made for. XLR handles long runs. One reason monoblocks are popular is for just this setup.

Long interconnect or speaker cable
My room configuration requires that my rack is off to the side of my speakers. This means I need to run 20 feet of speaker cable (Wireworld) from my Mc mono blocks. This makes high end speaker cable cost prohibitive.
I was thinking I could move the amps next to the speakers, have short higher quality speaker cables, and then a long run of moderately priced XLR interconnects from my preamp.
So, all things being equal, what’s better for SQ, a long run of lesser XLRs or speaker cables?
