My 2 cents;
You can't just give a budget and room size and ask for loudspeaker suggestions. Well.....you can but good luck! 95% of the time the people who respond to such posts just recommend what they have. Silly.
As others have said, you have to listen for yourself.
Case in point is the recent Axpona exhibition of a $2M system featuring the reigning flavor-of-the-month Magico and their flagship monsters coupled with D'Agostino electronics. Today's version of the S'Phile website features a rave review of the sound. Check the 'net and various Youtube videos covering the show and some very experienced industry insiders, dealers, and experienced listeners could not get over how bad the sound was. The set-up was in a very large room but the Magico's arguably were still overpowering the room but here is the key-different people hear differently. Somebody else's gold may be your dog shite.
One more thing-the very first response to your post recommended you get a huge subwoofer. News alert-going down to 20hz is not the be-all and end-all of good sound and it is not necessary for every listener. That is the hallmark, no offense, of not knowing much about this hobby. I recognize that false mental paradigm as my own when I was inexperienced at home audio. Almost 40 years ago I bought a pair of B&W 805's and falsely thought if I added a subwoofer I had all the frequencies covered and that was all I needed. Silly wabbit, trix is for kids!
