CON's
Not as musical
Top end can be harsh
Mid is not as fluid

Hi, Graeme and welcome- lots of lovely and experienced people here who can answer all sorts of hifi questions.
For me, the Devs can be as musical as anything out there- they have to be set up right
Right power (cords; maybe clean source)
Right supports (vibration dampening)
Then the highs are great, musicality flows and mid is plenty fluid although I have never considered exactly what that means so maybe take it with a grain of salt.
One pro you left out is imaging like magic. As they say in Ghostbusters "free-floating, full-torso, vaporous apparition".
Crappy power can indeed make upper highs less natural.
All the best.
