how much power to drive focus Audio fs 788

I just bought a pair of fs 788 (waiting for shipment), I previously owned the fs688 which where increadible, I used a simI-5LE to power the fs688, would the sim have enough power for the 788?
I would rather go intergrated but separates are not out of the question, I have reading about the jungson 88d, but still, enough power?
Any opinions would be helpful

I have a treated 13 x 16 x 8 room
thank you in advance
The 788's are easier to drive than the 688's, so if you liked the Sim I-5 with the 688's, you should be fine...
