Tekton DIs or Legacy Focus SEs?

Bill,
Good points, the AZ Crescendo has a ribbon tweeter and I'd say it sounds warmer than the Double Impacts.  Honestly I like both of these speakers very much. The Legacy appealed less to me but this is simply my taste. Surely someone else could definitely prefer the Legacy.  This is the beauty of High End audio, something for everyone. Plenty of good audio product available.

Agree às we both know  audio opinions are by default relative and subjective. Different listeners will have varying impressions, goes with the territory so to speak. This is exactly why if at all possible you have to hear these speakers or any audio product when the opportunity exists.

I wouldn't describe the DI  as warm either but it can preserve the full bodied sound if present in the recording.  But it can be somewhat tricky (in a good sense) with the DI  because they so reflect the driving amplifier.  So you can tailor the sound of your audio system by amplifier choice due to the lack of editorializing (well minimal) from the DI.

300b,845, KT 150, OTL, SS (bipolar or Mosfet) etc. You'll hear their individual distinctions with this speaker.  This is good in my opinion.

Dave,
I understand your point. Mac can answer this himself but I believe he was using SS and/or push  pull tube amplifiers with his Legacy speakers. He wasn't using the ZOTL or the SET  with the Legacy which wouldn't be best amplification option with this speaker.

I believe that Mac was using different power amplifiers with his Legacy speakers. The ZOTL and SET amplifiers are very viable choices for the Double Impacts as it is easier to drive than the Legacy. The DI allows a wider range of amplifiers to be used successfully.

There are very happy DI owners who use solid state (SS) or even class D amplifiers. Also happy owners using their lower power (tube or SS) amplifiers. One thing I noticed with the DI is with proper speaker set up/placement they can disappear in your room. These speakers really reflect the amplifier and all upstream components convincingly. Based on my listening the sound can really change depending on the chosen amplifier. So be aware that you’ll hear whatever the sonic character of your system components. Resolution is high but isn’t analytical, in fact quite a natural presentation.

Cohicks4,
As already suggested home audition if at all possible.  I've heard both speakers but not in direct comparison.  Tekton Double Impacts I find more musical , engaging and more natural/organic in sonic character yet exceptionally dynamic and lively. Audiogon member Mac48025 has owned both, email him, he has good ears and is friendly. 
Good luck, 
Charles
