Loudspeaker sensitivity and dynamics: are the two inexorably linked?


Have been listening to quite a few speakers lately, and increasingly I've noticed that more sensitive speakers tend to have better microdyanmics - the sense that the sound is more "alive" or more like the real thing.

The speakers involved include my own Magico A5's, Joseph Audio Pulsar 2's, and  Wilson Watt/Puppy 7's, as well as others including the Magico M3, Wilson Alexia V, various Sonus Faber's, Magnepan's,  Borressen's, and Rockport models (Cygnus and Avior II).

A recent visit to High Water Sound in NYC topped the cake though: proprietor and vinyl guru Jeff Catalano showed off a pair of Cessaro horns (Opus One) that literally blew our minds (with a few listening buddies).  The Cessaro's sensitivity is rated at 97 db, highest among the aforementioned models.  That system was very close to live performance - and leads to the topic.

I'm not referring to maximum loudness or volume, rather that the music sounds less reproduced and more that the instrumentation and vocals are more real sounding through higher sensitivity speakers.

Is this a real phenomenon?  Or is it more the particular gear I've experienced?

Thoughts?

High sensitivity folks (not efficiency)

Ive had lots of all the above (and still have many of both). One mans "dynamic range" is another mans "loud" or "in your face" so its a hard subject to discuss.

IME yes, high sensitivity = more "dynamic range"

There’s no way in hell the crossover is heating up as much as the voice coil!!

Think of thermal compression at 1 watt at 84db vs. 1 watt at 99db!! 
I’ve heard the difference hundreds of times…… the 84db (low sensitivity) sounds stuffy and congested with no dynamics. Doesn’t really matter what topology 

The volume (db) can be there with low sensitivity (with high wattage) but never the punch and drama…it’s just a wall of high db….
