Thanks for your input. I have a pair of Hegel H30 mono blocks. 1125 watts each and able to handle any load down to 1 ohm. I think they will be a perfect match for the 745s. My speakers ship on nest Thurs. Very excited and a lot of work in from of me building a new shelving unit as these speakers require a complete re working of my room. Connie just sent me a picture of the finished units. They are breaking them in right now.
