Yes of course I do have the Sonus Faber Cremona's, but not the auditon m's. I have had them for just over a year now. I got my pair second hand. never regrated it for one moment. I have the floor standers. OF course there is the the Cremona m's which are the small ones. I bought my pair with a unison amp. But just out of curiuosity decided to try them with my Marantz Sr6003 & was very surprise with the musicality i was getting.. The marantz amp has seen been in place.
If you can buy Sonus faber speakers i Would not hesitate at all. I have a recording studio & have listened to lot of speakers, but the faber's just sound so good to my ears. Then again it's a matter of taste & how you like your music to sound.
I would say the sonus faber's sound open, Smooth & rich sounding. The Audition m's basically have the same sound as the Cremona floor standings, But not as opened & not as big a sound stage.
If you can audtion pls do so before buying.
Good luck.
