This should be expected whenever the audiophile goes to dealerships or shows. There are hundreds of superb sounding systems out there. Some will connect better than the one we are currently using.
You have a choice; either put more money and time into redoing your rig, or buy the speakers. But, there is no guarantee those speakers will sound better with your gear. The shop has optimized the system, whereas unless you buy the entire rig you will have to go through the same process via a different route.
Frankly, the considered change looks to me more like a sideways move than a big step up. You will lose some attributes of the SF in the process, and you may regret it. Both are very nice speakers, but you may wish to redo your electronics and cables to achieve better results. My guess is you haven't come close to maximizing the speaker you currently own.
