Should I use long interconnects, or long speaker cables?

Currently, my equipment rack is placed centered between and behind the speakers.  I’m getting acoustic feedback (rumble) from my tt due to it’s location.  Successfully, I have eliminated this rumble by using a KAB rumble filter.  However, this seems to me like a bandaid approach, and I would like to try to eliminate the use of this filter if possible.  I’m thinking of moving my equipment rack to the side wall to try to eliminate the rumble filter.  My question is, there are two ways to do this.  Is it best to:
#1). Move everything (including the amplifier) to the side wall, and use long speaker cables to connect the amplifier to the speakers.  
#2. Move everything, except leave the amplifier on the floor (on a separate amp stand), and run a long interconnect (20’-25’) from the preamp to the power amp (my preamplifier is single ended only)?
In advance, thanks for your guidance!

That's because all the most rigorously controlled experiments prove the best most efficient geometry is daisy chain. Especially when used with super high end outdoor speakers. A few listeners claim to hear slight degradations but they were using super ultra crazy higher end indoor speakers, and also not properly double blindfold testing. My one question is how were you able to daisy chain cable and anti-cable without them annihilating each other?

The rumble could simply be the fact that your tt bearing is worn, which means changing the cables will not make a difference.

As for cables, both for speakers & interconnects, the shorter they are, the better they are.

@louisl I can confirm that the Nobsound springs that @millercarbon recommends fixed this exact problem for me. I was skeptical but after trying EVERYTHING to eliminate the rumble the springs actually worked. Good luck!

The key to eliminating tt rumble is 3 things...Isolation Isolation Isolation. You simply cannot isolate enough. Mounting a tt on an exterior wall away from the speakers usually does the trick. I have had great success with this in addition to using Sorbethane  cones under the shelf and used cork isolators under the tt  feet.  I am also big on short as possible speaker cables and long runs of "Balanced" interconnects. I have monoblocks and have used this method for years without fidelity loss of any kind. 
Good luck

Richard Vandersteen has actually tested this theory not just offered an opinion. His results are shortest speaker cable you can possibly run. If you need long runs make it the interconnection cables to components.
