The Legacy Signatures are very up to par with the larger Focus, the difference is the amount of deep bass and a slightly bigger soundstage and the Focus play louder, but other than that the two speakers sound the same.
In terms of warm, yes the Tekton's are warm, in fact most soft dome tweeters made by anyone tend to be on the smooth ie warm and slightly recessed side of sound, while ribbon tweeters, AMT, and exotics Ie Beryilium, or Diamond tweeters tend to the high resolution side of the sonic specturm which can also be a good or bad thing depending on how they are matched.
I heard the DI on $60k worth of very high end electronics and they sounded great, but were definately on the warmer side of the spectrum also on the Zotel amps same thing. The speakers do have a characther, as I mentione before they the Tekton's sound fanastic as well and we are looking to bring in the Tekton Di SE as well.
Mac I don't know if the amps you had worked well with the Legacy's or your system wasn't voiced to bring out what the Legacy's do.
I will still contend my findings are pretty accurate between the two speakers, this is a battle of the ages, for both systems are terrific and each one has its own strengths which I summarized before.
As I commented before warm isn't a bad thing at all, it is how Eric voiced the speakers. compare these to a set of speakers with any of the above drivers and you will come away with the warm side of neutral.
As per the Legacy's working in a small room our demo room is 18 by 14 which isn't a giant room and they sound fanastic.
