This person makes some very nice and affordable cables. I use his interconnects and I am very pleased with their performance.

The best advise is of course , to loan cables to see what fits your  taste best.
So if you have a dealer near you , ask him about the subject 

There are many great cables out there , and not knowing your budget and what you have now , makes a recommendation very hard.

Thanks for reply guys my budget is under 1500
and now I use audioquest rocket 33 biwire.

I am biwiring a pair of 85db efficiency Vandersteen Treo CTs with Clear Day Audio Double Shotgun Cables.  With your 90-db efficient speakers, 2 pairs of the shotguns may be right for you.  Best thing you can do is call the designer/manufacturer Paul Laudati at (520)-743-7941.  He loves to talk to prospective customers about their systems and the sound they are trying to achieve.  His speaker cables are all pure silver conductors.  They are not at all bright sounding, just very open and detailed.  The worst that will happen is you'll have a nice conversation with a true gentleman.  All the best!
