Sonus Faber surprise

emiliop, yes, of course you are getting adjsted to their sound. Speakers do not appreciably change their sound with use. We adapt to their performance. As you get used ot their sound the acoustic memory of the other will fade and you will increasingly appreciate the newfound resolution. The situation is typical, and everyday thing. 

I hope you're even more happy the longer you own them and with the right amplification they should be a lot of fun. I've also found SF overall to be less fatiguing and more musical, (sometimes at the minor expense in other areas).

I could easily see myself owning one of their models if wasn't happy with my older used Raidhos. I do enjoy the clarity and finesse of the D2s a lot.  Have fun!

I would add, on a separate topic, that I purchased brand new Scansonic MB2.5 floorstanding speakers (which forced the used Raidho purchase later).

I disagree 100% with the fact that break-in of a loudspeaker is a myth. The small MB2.5 woofers needed the mechanical break-in, and over hundreds of hours they lost their orginal leanness, sounding much better. But if it's not hearable to others; that's fine too.

Totally NOT a myth. Material science. 

Found out something interesting tonight. My tube integrated amp has a switch on the back. According to the manual it is a gain switch but works by varying the feedback. The high gain is high feedback, the low gain position is moderate feedback. It also has a central position that the manual says is intended for engineers but can be used to listen to music. This position is 0 feedback but strangely enough is the highest gain. I was listening to SF Concertos in high gain and triode mode. When I tried low gain the speakers suddenly sound like I expected SF to sound. In the central position sounds like I poured syrup all over my speakers. I am still experimenting with high and low to decide what works best for me.
