Opera Speakers - Opinions?


Does Opera have a "house sound"? Are the 1.5s and IIs (which I understand are now out of production) on the warm or cool side of things (musical or analytical)? Or are they neutral, or warm neutral, cool neutral? Can the Callas' be used in a small room with only 20" from rear of speakers to the wall? I ask since they are reat ported. Do they look as good in person as on their website? How do they compare to, say, Sonus Faber and Silverline models? How easy are they to drive? Thanks, people.

Tomryan,
The Silverline's are, using your adjectives, lusch neutral. They are a very warm sounding speaker. I listen mostly to jazz & old rock, ie the doobie brothers, joe cocker, eagles. If your taste is hard rock they might not be the best for you. I did forget to tell you I have the speakers close to the wall and have no bass problem. I have hardwood floors but the room opens up on two sides behind me.
Thanks, guys. I've always heard that the Silverlines were on the musical as opposed to analytical side of things, which is where I like it. I think I've just become enamored of the Opera looks.

Yohjo - I see you use Rogue amps for power. Have you ever or do you know of anyone who uses SETs with Silverlines? I have an Air Tight 300B amp which I just can't seem to get rid of. That beauty thing again. It won't properly drive my Harbeths which I also love, and am looking for a second speaker for different moods.
Tomryan,
The only set amp I heard drive the Sonata's was the one Alan makes, but not for sale. I heard it at his offices. It was wonderful.
I did forget to tell you about the finish of the Operas. They are good looking but I did not have my first choice in finish. When my girlfriend saw the Sonatas she remarked how beautiful they were. But she did not see the Opera's.
