Magnepan LRS compared to the .7 or the 1.7i ?

With all the hype about magnepan’s new LRS, I am wondering if anyone has compared them to the slightly bigger and slightly more expensive .7 or even the 1.7i?  (I assume they are better than the MMGi that they are replacing, so no comments about these two are necessary.)

I suspect they are new enough that there may not have been many chances for such a comparison.  

So, lacking a side by side, I wonder if anyone who heard them at Axpona or otherwise (I was only there Friday and missed them) is familiar enough with the other Maggies to offer comments/thoughts/opinions between the LRS, .7, and 1.7i.  Comments from dealers who sell Maggies are welcome.

finally, brief conversation with one area dealer suggests they will be more of a factory direct item that he will not carry, while another area dealer hoped to get a pair but did not know the time frame. Has anyone heard a more definitive story on availability?
