I recently changed speaker cables between my Threshold S/500 II and Thiel 3.5's from Alpha-Core MI 2's to Alpha-Core MI 3's. Well let me tell you, from what started as a sort of let's see what happens, without any serious expectations, has turned into a wonderfully pleasing surprise. I really liked the MI 2's in my system, but, was bothered by a slight tilted up glare that showed up on poorly engineerd recordings most obvious with music featuring piano. I was contemplating component changes. The MI 3's spread the spectral balance downwards, filling in the upper bass/lower midrange, eliminating that glare, adding warmth and detail to the bass region (yeah, I know it sounds like a contradiction, yet it's true) and spreading the back of the soundstage. I am now finding myself lowering the volume control on my Threshold FET 10 HL a couple of notches and achieving greater bass control yet with similar apparent over all volume. All this wth the same extended sparkling treble, sans the glare. Simply amazing! I've never enjoyed my system more. The MI 3's were considerably more expensive than the MI 2's, but are still a remarkable value compared to what other manufacturers are demanding. FWIW, Thiel uses Alpha-Cores and Alpha-Core uses Thiels. I can't imagine why they wouldn't work with Levinson.
