Speakers sound too bright.

You said your KEF were too analytical/metallic. The KEF concentric driver is not metallic sounding, just the opposite. It's extended but not harsh at all. So, will will never like the ML ribbons. Send them back and get something more mellow. 

Yeah, if they dont work out, will probably try Lintons next.  For now, I'm going to give it 30 days and make a decision at that point. I have 60 days to return them.

I have played with ML speakers for decades and a few things to keep in mind are: 1) They are line sources that radiate in both directions and 2) they are a capacitive load not a resistive load.  

When I looked up the OP's speakers, they are conventional box speakers with dynamic drivers (magnets, coils and cones) plus an unconventional tweeter!  A far cry from the MLs of old ...

Try Kimber Kable 8tc.Will add warmth to your sound.

I really liked my Lintons. I'd like to hear the new Super Lintons.
