I have not, but I think you will find better pairings, especially if you listen at decent volumes. I am sure it will sound very pleasant, but if you A/B'd against against a more powerful amplifier you would hear a huge difference.
I lit up a pair of LS50s last week with a Musical Fidelity a1008 integrated that can swing 75 amps of peak current and it sounded far better than a Primaluna Prologue classic that was driving them prior. It was also a huge improvement over a Bel Canto c5i. You could tell they really responded to the additional power.
The Kefs are rated for 8 ohms, but they have impedance dips that makes them mate better with an amplifier that can easily handle a 4 ohm load. They are 85db sensitive, which is borderline low.
On paper it is not a great match, and based on my experience they really do like power.
