Alpha Core Goertz MI 2 upgrade

Thanks for your responses.
Unsound, may I ask what differences you heard between the 2's and 3's.
Thanks!

I also own single run MI-3, which I still use in one of my systems, and find them to be outstanding at providing those extra attributes you seek. Personally, never any problem, but check old archived discussions where Audiogon guru, Sean, pointed out his thoughts about greater ease of use and high quality with the smaller gauge MI-2.
In sequential open comparisons with MI-3, Reality Cables revealed more detail, three-dimensional cues in the soundstage, and bass slam. However, MI-3 quite spectacular in its own right if you want to stay with your present manufacturer. Although one factory rep to whom I spoke did not feel there would be a significant sonic difference, I also thought MI-3 bettered their MI-2.
If you are adventurous, check with Audiogon member, Clearsound, who sells Reality Cables for high quality systems, or realitycables.com

Greh, for me the MI 3's seemed to center the spectral balance. The MI 2's seemed to highlight the upper frequencies. The MI 3's are both warmer and tighter in the bass (I know it sounds like a contradiction, but, never the less it's true). The bottom of the MI 3's are more dynamic and powerfull. The MI 3's midrange is richer. The MI 3's seemed to allieviate some hardness and glare in the low to mid treble. The MI 3's still share the clear open sparkle of the MI 2's. I would have kept the MI 2's but Alpha-Core strongly recommended the MI 3's with my current amp. The MI 2's made more sense to me with it's higher impedance, but, Alpha-Core was right. The MI 3's seem to allow the bigger amp to really take hold of the speakers.

Unsound,

What would you think about bi-wiring with MI-2 and MI-3? That is, I would run MI-2 to the HF posts, and MI-3 to the LF posts. Would you expect that to create any problem?

I am running Legacy Signature II speakers, which are bi-wireable and go down to about 22hz.

Thanks to all for your responses!
