Synergistic Research Atmosphere level 1 or ????

i have pretty much convinced myself to purchase the synergistic research atmosphere level 1 speaker and interconnect cables. these are at the cable company. $519 for the interconnects and $579. for the speaker cable. what I don't know is what to compare them to before I purchase. let us stop this wheel of cables! I use a rogue stereo 90 super magnum with a shrimp pre and a musical fidelity m1 transport with a wadia 121 DAC. Vandersteen 2 signature speakers.
