I have had both and also bought the Concerto's thinking they would better the Concertino's. I listen to light jazz and female vocals. Sold the 805's and the Concerto's and have never thought about parting with the Concertino's. I think there is better detail and low end on the Concertino's over the 805. The 805 is a great speaker but depending upon placement it will vary.
This has been my experience only, I am sure you will get different views.
