Your Focal 836V's are 8 Ohm speakers with a fairly high sensitivity of 92 db. A very easy load for an amplifier to drive. You will have no problems whatsoever driving them with your M3i.
Same answer for the Focal 726V's too as you seem to have started two posts asking essentially the same question.
