Martin Logan SL3 with Musical Fidelity KW 500?


I am keen to change my Primare A 30.1 since I have upgraded my speakers to a pair of Martin Logan SL3; I previously owned a pair of Sonus Faber Grand Piano Home with great results, and was a good match with my integrated amp.
But I am aware that SL3's like lots of power, and I am shrinking my decision on a Musical Fidelity KW500, but I also know that it is a bridged amplifier.
I read on some reviews that you shouldn't use grounded loudspeakers with bridged amplifiers,why is that?
Is there a way to get around this problem? Maybe unground the power cables for the Logans?
Thanks for any suggestion, cheers.

I did a lot of testing amp's in the past with the SL3 for my work. And MF is a very good match.
Thanks for the reply; it is dual mono but built bridged already.
Yes I think ML and MF should be a good match, just worried that I may fry the loudspearkers/amp with the KW 500.
Cheers
