Mani -2s are great speakers but they are very power hungry. Use what you have right now and scour the Internet for a pair of B&K M200 monos.
This is an older model from the 90s but is robust and provides plenty of power.
Good luck and enjoy your Mani's. I envy you. Unfortunately,Mani's would probably overpower my listening space. I have a pair of Totem Hawks.
