Same here Kanta 2s for about 3 years
When I bought them they were side by side a pair of Spendor floor standers
The Spenders had a way way deeper soundstage. Never experienced anything like it.The Focals you mention still have a lot of the same components
an design which will give a a very detailed forward sound. Modern sound if you will.
The Sopras will be very revealing and transparent and I have been very happy with the Focal sound profile
Make sure you match amplification and good cables
Hope you get what your looking for
