long i/c run...looking for high end cable


I have a 40ft i/c run from my h/t processor to my monoblocks which are in the front of the room. I've heard that Synergistic Research is one of the best high end i/c for very long runs? Any thoughts or other suggestions? I will be auditioning a pair next week as well as a pair of Vahallas.

thanks,

I will definitely be using balanced cables...I should have listed the amps and processor...amps are Levinson 436's processor is ML No. 40, speakers are Revel Salons.

thanks again,

I'm using 22 ft long Harmonic Tech Truth Links unbalanced. Not a real expensive cable to be sure but they sound better in my system than some much more expensive cables i've tried. I have had no noticible increase in noise floor since i went from 1.5 m run to the 4 m. If your amp and preamp aren't truely balanced in their design, having balanced inputs isn't evidence of a balanced design, the balanced cables may not help.
Since you seem to have the scratch why don't you order a balanced Innersound cable from their website? Then you will have a backup and a baseline from which to compare the expensive cables. If you look at my system I am very happy with my Innersound (8M) - you'll need 10 or 12 M I think. The Innersound is built on sound engineering principles.
You'll be surprized but Canare pro-grade balanced cables available at Sam Ash Music store will do the trick with long runs at measurable price paid.
And I thought my 4 m. run was long! I have been using the Stealth PGS-3D from Interlink. It is gold litz and excellent. I would prefer Siltech G5 Compass Lake were I Bill Gates. I have tried Pure Note, Jena Labs, and several lesser cables in my 4 m. run, but have found nothing close to the Stealth.
