I found the perpetrator. Here is the mugshot:
Like I mentioned before, I got the LSi-C and the new cable on the same day. The Canare always require 1-2 days break in time. I left it playing overnight, but didn't check in the morning if there was an improvement. Now I reconnected the LSi-C after some break in and sound was improved. It matches the LSi-9s now. One problem didnt go away (and I dont think it ever will) - its this boxy, nasal quality to the LSi-C. But if you compare the LSi-C and LSi-9, the enclosure quality is far superior in the LSi-9. Its is simply formidable. 1.5 inch sides, heavy as hell! Lsi-C - not so much. So, what would you expect?
Comparing the old Bic America and LSi-C after speaker cable break in left me with this impression. Bic America is loud, bright, in-your-face so to speak. I can crank it up to +20 and get tired after 10 minutes (all other channels defeated). LSi-C is different. It is understated now, not mute or even shy. I can crank it up to -7 and listen to it for about 40 minutes before I get the sense of fatigue. But the main difference is in what I hear. The crash of cymbals are suspended longer in the end. The instruments are more vivid, detailed, then dont step on each other.
Its like having two guests for dinner. One is loud, obnoxious, demands attention, grabs you by the arm, tells you at first entertaining stories until you realize in a few minutes that they are all lies. The other guest is silent until you mention that you have a problem lets say with the the car, or the IRS, or whatever. He says "I can fix that" and somehow he does. Which guest would you love to have around next time?
That is what LSi-C became after cable break in.
