Are MIT ic's warm sounding?

MITs are very good, perhaps even exceptional on clarity, even the lesser models I've used.

Not warm but more full due to increased clarity.

Well your interconnects are way out of my league I think, but I've used MIT terminator 2 and 4 interconnects. I would not describe them as warm at all, in fact the opposite. I'd agree with the micro dynamics and space observations.

For a warmer sound I use DNM Reson interconnects. I much prefer these currently over the MITs on my system.

These are a radically different design approach from most high end interconnects, almost a minimalist design approach. You might well do better but it would not take a large investment to give them a try. essentialhifitweaks on ebay usually has them available.
