Jimbones, you say that you found the MIT MH750 not be clean/clear, which I agree with, however, you also say that you found it to sound forward and bright, which does not jive at all with my memory of this cable. It had a large, deep stage, but was a bit darker sounding.
Anyway, if you are looking for a laid back sound, I would skip the Analysis Plus cables. I found them to be very clear with good tonal balance, but very forward sounding cables, perhaps the most forward sounding cables I've heard. I had the Solo Crystal Oval 8's. You say that you are looking for laid back, smoother and cleaner sound. In my experiences, laid back and cleaner generally do not go hand in hand. They are heading in opposite directions. Cleaner sound generally occurs when the leading edge of the transient is quick, these cables also tend to have a quicker decay of the note as well, which leads to a cleaner sounding, more immediate (forward) presentation. The cables that sound laid back, which offer good stage depth, offer a slower, more natural decay of the note, though the downside is that they also are not as quick on the leading edge transient of the note. Just as one cannot find a full, warm cable that is also articulate and fast, laid back and cleaner tend to drive you in opposite directions.
If cleaner is your top priority, then the Analysis Plus may work for you, as they are smooth and clean, yet NOT laid back. You may want to try Tara Labs, Purist Audio, or Stealth if you want laid back. The Tara Labs and Stealth will be cleaner, though if you found the MIT cable to be bright, you may also find Tara Labs and Stealth to sound bright. Hell, even Analysis Plus will sound bright compared to my experiences with MIT cables. MIT are much like Cardas and Purist Audio, known for their fuller, deep 3 dimensional stages, yet rather dark sounding with some gear.
