I also have a similar set up, but keep shorter speaker cables (6)', amp resides between speakers, and running longer ICs( 15') from amp to source.
Hope this helps.

Speaker cable length
I have Cary tube amps and Harbeth speakers and I am kind of limited as to the placement of my components in my listening room. The optimum positioning for best sound would require a 27 foot speaker cable on one side and an 18 foot cable on the opposite side. Are these runs to long and could they harm my equipment or somehow lower sound quality?
