Atma-Sphere with which speaker cables?

Hello Everyone,
I am driving a pair of Dali Megaline speakers with a pair of MA-2's and a Krell. The MA-2's are presently driving the ribbons and the Krell drives the woofers. I am awaiting a pair of MA-1's which will replace the MA-2's on top and the MA-2's will be moved to the woofers.

I have been using a pair of Alpha-Core AG-2 and MI-2 cables which sound good. However, I now need to reconfigure the equipment area and will need to purchase longer speaker cables. I have read that Alpha-Core cables, at least in theory, do not work well with amps that have high output impedance, and one post seemed to be saying that anything over 1 ohm is high. The MA-2 has an output impedance of 1.75 ohms and the MA-1 has an output impedance of 2.3 ohms. The nominal impedance of the speakers is 6 ohms. I have heard, but have been unable to confirm that the impedance of the MI-2 cables is 2.5 ohms and I do not have any information about the AG-2 cables.

I am curious to know if the Alpha-Core cables do mate well electrically with the Atma-Sphere amps, and I would also like to hear which speaker cables other Atma-Sphere owners are using. I would rather not spend a fortune on cables at the moment, but I look forward to hearing suggestions for both reasonably and not so resonably priced speaker cables. Thanks in advance for your time and suggestions.

All the best,
Dennis

In conversation with Ralph at Atma-sphere he stated that he is using Mogami Neglex cables. I suggest you call Ralph and get his ideas for your situation.

I use JPS Labs Superconductor with M-60 II.3's and find them stunning through the entire dynamic range. My runs however are only 8 feet.

Hello Entrope,
Thanks for the response. Actually my cables will only need to be 8 feet in length. The Alpha-Core's I am using currently are 4 feet long, and as I mentioned sound good with the Atma-Spheres. However, I do not want to invest in longer Alpha-Cores if they do not match well with the amps electrically. My thinking is that I may have gotten away with a mismatch since they are only 4 feet long, but that increasing the length to 8 feet might make any mismatch apparent sonically. I appreciate hearing about your specific experience and satisfaction with JPS Labs Superconductors.

Hi Dennis,
Boy I wish I had your problems. I'm also using the MA-2's with Soundlab A-1's. I found the Magnan speaker cable to work quite well with this combo. I personaly didn't care for the Alpha Core in my system. Good luck.

I switched to Omega Mikro Planar V active cables from the Alpha-Core AG-3 cables with my MA-2s and Eidolons. Huge improvement with the Omega Mikro, highly recommended.

I'm using Shunyata Andromeda Helix between MA-1 mkIIIs and Audio Physics speakers.
