Sorry Crankshaft, just saw your ?.
Don't know if this makes sense to you, but the druid are extroverted in nature with a good dose of introverted-ness; and the tekton are introverted with a good dose of extroverted-ness. The tekton are more resolving and allow you deeper into the music...where it becomes easy to be one with the music;..with the druid, you are the listener of good music.
As much as I appreciated the Druid, the Tekton are clearly superior with acoustic music and vocalists. More natural sounding & true to life. Especially with guitar, cello, woodwinds, saxaphone, piano, & vocalists.
On some recordings with trumpet or massed strings, the tekton ribbon tweeter just isn't up to the task, with occasional brightness at the top end. And on rock from the late 60's - 70's, the tweeter grabs the electric guitar with poor results. These issues were only on moments or sections of the music and generally on recordings with poor sonic quality (the tekton are very resolving and excel w/ sacd, vinyl, & good recordings.) With the druid ribbon tweeter this was even less of a problem, with only rare moments of brightness.
That being said, the druid were generally good with any type of music and bettered the tekton on R&R. Had the druid for a year & enjoyed them, but kept the tekton instead and never regretted it.
I think that the kats meow have a soft dome tweeter, so they will not have the same upper register issue's that I occasionally heard with the tekton.
Can recommend either depending on your tastes, system, & room;..but I preferred the Tekton. Enjoy, it's all good!
