Which speaker is better

I know you asked about the three, but their sonic qualities are similar to Revel Studio and Salons. I would suggest listening to these before making a final decision. I have the studios and compared them to the speakers on your list. All of these are excellent speakers I just personally liked the midrange on the Revels better. I felt that they had some of the revealing qualities of thiels which I also respect along with the midrange and a more robust sound stage for my taste.

Sonus Faber

The SONUS FABER Guarnieri Homage. It will have more resolution in the midrange, where most of the music is, and it will sound like music. You will be happy using an ordinary amplifier (greater than 100 watts please) and ecstatic if you pair them with any of the finest amplifiers in the world. The Guarnieri is world class. The other speakers are just nice in their price range.

Enjoy!

I would consider Verity Parsifal monitors and Merlin TSM's as well.

Fertin (full range)combined with a good sub, is as far my premier choix, sacond is ESS Heil, That's it.
