Cables and the Martin Logan CLSIIZ's

I'm using Straightwire Rhapsody II Speaker cables and interconnects.
Also have Cardas Neutral Reference and Cardas Quad Link 5C interconnects. Tried them all but the total Straightwire package sounds best, detailed without losing the "bottom end". Used Jenifer Warnes The Hunter and Siris Svale Band Cd entitled Blackbird(an icredible disc) among others for evaluation. After much positioning and small incremental moves in the sound room I am pleased with the spacious sound stage and "low frequency performance". Wondering what others in the forum are using and especially interested in the rake angle(tilt of the panels relative to the floor). Thanks in advance to any and all who take the time to reply.
