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

Mogami Neglex interconnects between MP-1 and MP-2 sound as good as PAD Dominus (amazing, but true), whereas the Speaker cable tests between MA-2s and Kharmas 3.2s revealed only one clear winner: PAD Dominus.
I tried the Goertz Alpha Core with the AS and they are very good. Very fast, dynamic with excellent bass. The Dominus is just more lush and rich in the upper mid-range and the backgrounds are blacker.
