Thinking to upgrade speakers

Like STHLM78, I am also a big fan of Concentric drivers and currently own and listen to KEF Blade 2's and LS50's. I also own a beautiful pair of Focal Electra 1028 BE speakers, which I adore! When I auditioned the Focal speakers, I listened to the Kanta no. 2, Sopra 2 & 3, Electra 1028 &1038 Be. I liked them all, but my favorites were the Sopra 2 &1038 Be, which were very close in sound and feature similar drivers. I purchased the 1028's because they fit better into the system configuration and my wife did not want anything as large or visually commanding as the Sopra or 1038 (she loves the 1028). If you have a chance to listen to the 1038 Be speakers. do so. There were some terrific close-out deals on the Electra line which may still be available. I also highly recommend the KEF Reference, Blade and R series speakers at their given price points.

@transnova lucky you! I am so jealous :) never heard Blade but have a pair of KEF LS 50 wireless and compare to their size and price, they are really good! one question refer to KEF blade 2, do they sound nice in low volume ? How much free space need from side and back for clean sound ?
@toetabaudio, thanks for bringing up Boenicke namn, saw reviews on net and they need space to breathe and I don’t have room for that! Btw, among high end slim speakers, Audio Physics ,PMC and Boenicke are my favorites.

Sadly I removed SF and added Zu Audio Definition , Spaitial X2  and German physiks HS130 to my list! 
I am wondering why here Lagacy Audio is so popular, almost in all discussions about new speakers , someone recommended them, though their appearances not my taste but badly want to check them too!

the salon 2 would be the most accurate but need gobs of power seriously 1000 wpc would probably be safe then careful set up, but I think they have the highest ceiling. Focal Sopra's would probably be the easiest for me to get the best sound out of and don't require an arc welder to drive them. SF sound if they're like they used to be are warm sounding so the room could make them sink or swim. We tend to recommend what has worked for us and the reason there's no repeats is all our rooms and systems besides our own personal taste make speakers sound different. buying without a home demo is like throwing darts with the lights off.

sthlm78, You are doing very well. I think the powered LS 50s are better then I can make my passive LS 50’ssound with any combination of amplifier, pre-amplifier, or DAC.  The blade twos   are surprisingly versatile. I had them in my 12 x 14 office powered by a Rogue Atlas Magnum amplifier and they did not overload the room. They were a few feet away from the corners, however closer to the back wall than you would want them to be. In my main to channel system I am able to get them a little further Away from the rear wall, but they are only 2 to 3 feet away from the side walls. I find the results are still excellent.
