@suboost - I think @mtbiker29 and I are thinking along similar lines. My thought process was that if you think the Focal 936 is a significant upgrade over your current speakers and you're setup for both stereo and home theater that the Kanta's would be a mismatch with your current setup.
I've heard my 836v speakers connected to everything from an Onkyo receiver all the way up to Krell monoblocks that were intended for the Grande Utopia speakers. I'd have no issue with upgrading my integrated amplifier knowing that my speakers still have more to give.
I do generally subscribe to the theory of buying the best speakers you can afford assuming that you love their sound. You can then upgrade your equipment to maximize that sound. A caveat to this theory is that it's a waste of money to have speakers that are far superior to the rest of your system unless you have a plan to align things over time. My current system is approaching the limit for the amount of money that I'm willing to invest in this hobby and my setup limitations wouldn't allow me to truly benefit from significantly better equipment.
