The la50w suggestion is a very valid one. Would take the guessing out of getting the most out of whatever passive speaker you might choose. Ls 50s driven well are top notch within the limits of speakers their size. Ls50s not driven well will not get you the full benefit.
I have ls50s and have not heard the Regas nor those specific Totem but I suspect each sounds significantly different.
You will need a sub for full range with any of these smaller speakers if that matters to you.
So other than you have an active option with the KEF to assure they are driven well, I think will come down mostly to personal preference.
