Transient vs. Analysis Plus

My system is configured with fairly long speaker cable runs (approx. 10m) due to the physical layout of twin parlors in an old house.  I'm currently using Transient cables with 12-2 bricks at the speaker end.  McIntosh MC 275 amp/ Golden Ear Triton One speakers, which I'm hoping to upgrade to One Reference.  I read in an informative thread awhile back that it might be more effective to shorten the speaker cable runs and lengthen the interconnect from preamp to amp.  I could position the power amp below the floor in the basement between the speakers and reduce the cable length to 2m.  Any thoughts there?  Also curious to compare Transient to Analysis Plus cables.  Thanks.
