3 speakers to consider.

I would pick the 340 because it doesn't have a metal tweeter.

+1 on the Dyn Focus 340 - heard the Revel F52 and it seemed very dry sounding to me and lacked low end punch. No experience with the Montana.

Just my opinion

I think Dynaudio is the best , their engineering is second to none, even there lowest cost speaker shows their commitment to the best in reality of sound reproduction........

Montana without any doubt. Why? Have owned them all,and Montana blows them both in terms of realistic portraying the music, that is height of performers to a natural size, (which a quite many high end speakers are not able to), weight in music, and the actually sense of realism in voices and instruments.
I upgraded my Eps 2 to Was recently, even though I could easily have lived with the Eps 2 for many many years. Properly set up, they will provide you with fantastic music, bass that goes deeep and fast, dynamics in world class only surpassed by some few speakers costing 10 times as more and seamlessness which are far ahead of the other two.
