Enjoying My New Focal Sopra No2's

The Sopra's sounded awesome in my "man cave", without the sort of low bass I enjoy in adding sub woofers, but the bass the No2's have I found to be very tight, detailed and not at all "boomy".

Now, once I added the subs, the bass they produce in that room, was very boomy.  It took a lot of fiddling with positioning, settings, bass traps, etc. to get the subs properly integrated and not sounding boomy.  But the Sopra No2's bass (as low as they go) sounded really excellent, again...in my room.

Thanks for the responses. The Focal Sopras have received a lot of great feedback from current owners. Further investigation revealed that they are the European speaker of the year (2015) having won the EISA award. Since there are folks who reported great success driving the Sopras with Naim amplification (I happen to own some Naim amps), these speakers have got me interested. The build quality is superb and form looks classy and elegant. That is one of the reasons I got attracted to these Sopras. Sound-wise I presume they will be fantastic given the pedigree of these classy French speakers. Will need to give them a listen sometime.

Toneranger....I didn't try the Simaudio 600i, so I can't comment on how it would work with the 
Sopra2. 
I have a relatively small listening room, but a huge space (cu. ft.) to fill due to a cathedral ceiling and loft above my listening area. 
My 700i loafs along driving the Sopras. In a normal room without the volume to pressurize, I'm confident the 600i would be awesome. 
They are both sweet sounding amps.

I recently heard the Sopra 2 at a New York dealer.  He had them 3 feet from the back wall and away from the side walls.  Were driven by McIntosh equipment.  I loved the soundstage, but the bass was boomy.  I've read the Focal includes a bass plug to tailor the bass response.  Does anyone use it?  I really want to like the Sopra but if i can't get reasonably flat bass response I will look at other speakers.  thanks
