Acoustic Zen Adagio - need advise please

Hello everyone,

Time for speakers upgrade and I have almost decided to go for Adagios based only on what I read about them.
I know that buying speakers without auditioning them is not a good idea, however I have no much of a choice.
In the place I live only few brands are represented and I could not find anything to my taste within my price range.
My last speakers were Dynaudio 1.3SE and despite being very good in some areas I did not like their synthetic and bright overall sound and got rid of them.Temporarily replaced them
with LS3/5A and love them,but they are too small for the room my main system is in....so it should be a floorstander
to replace them.My room is 22x11x9.
My questions about the Adagios are:
1.Can Adagios be labelled as alrounder as I listen to wide variety of music genres? How will they handle hard rock for instance?
2.Is the box absolutely quiet without any resonances, feedback etc?
3.Do they come close to single driver ,paper cone speakers
in terms of natural timbre,size of instruments and presence.
4.Are the factory boxes safe enough for overseas shipping.
Some time ago I had big speakers damaged in transit(very poor packaging) and do not want this to happen again.
5.If you may suggest any other speakers up to $4500 which
come close to above stated please advise.
Thank you very much.
